•
•
•
•
•
•
The OPA322 series consists of single, dual, and
quad-channel CMOS operational amplifiers featuring
low noise and rail-to-rail inputs/outputs optimized for
low-power, single-supply applications. Specified over
a wide supply range of 1.8 V to 5.5 V, the low
quiescent current of only 1.5 mA per channel makes
these devices well-suited for power-sensitive
applications.

The combination of very low noise (8.5 nV/√Hz at
1 kHz), high gain-bandwidth (20 MHz), and fast slew
rate (10 V/μs) make the OPA322 family ideal for a
wide range of applications, including signal
conditioning and sensor amplification requiring high
gains. Featuring low THD+N, the OPA322 series is
also excellent for consumer audio applications,
particularly for single-supply systems.
The OPAx322S models include a shutdown mode
allowing the amplifiers to be switched from normal
operation to a standby current that is typically less
than 0.1 μA.
The OPA322 (single version) is available in SOT23-5
and SOT23-6, while the OPA2322 (dual version) is
offered in MSOP-8, MSOP-10, SO-8, and DFN-8
packages. The quad versions OPA4322 come in
TSSOP-14 and TSSOP-16 packages. All versions are
specified for operation from –40°C to +125°C.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5 V beyond the supply rails should
be current limited to 10 mA or less.
Short-circuit to ground, one amplifier per package.

Ensured by design and characterization; not production tested.
Disable time (tOFF) and enable time (tON) are defined as the time interval between the 50% point of the signal applied to the SHDN pin
and the point at which the output voltage reaches the 10% (disable) or 90% (enable) level.
Full shutdown refers to the dual OPA2322S having both channels A and B disabled (SHDN_A = SHDN_B = VS–) and the quad
OPA4322S having all channels A to D disabled (SHDN_A/B = SHDN_C/D = VS–). For partial shutdown, only one SHDN pin is exercised;
in this mode, the internal biasing and oscillator remain operational and the enable time is shorter.

APPLICATION INFORMATION
OPERATING VOLTAGE
The OPA322 series op amps are unity-gain stable and can operate on a single-supply voltage (1.8 V to 5.5 V), or
a split-supply voltage (±0.9 V to ±2.75 V), making them highly versatile and easy to use. The power-supply pins
should have local bypass ceramic capacitors (typically 0.001 μF to 0.1 μF). These amplifiers are fully specified
from +1.8 V to +5.5 V and over the extended temperature range of –40°C to +125°C. Parameters that can exhibit
variance with regard to operating voltage or temperature are presented in the Typical Characteristics.
INPUT AND ESD PROTECTION
The OPA322 incorporates internal electrostatic discharge (ESD) protection circuits on all pins. In the case of
input and output pins, this protection primarily consists of current-steering diodes connected between the input
and power-supply pins. These ESD protection diodes also provide in-circuit input overdrive protection, as long as
the current is limited to 10 mA as stated in the Absolute Maximum Ratings table. Many input signals are
inherently current-limited to less than 10 mA; therefore, a limiting resistor is not required. Figure 30 shows how a
series input resistor (RS) may be added to the driven input to limit the input current. The added resistor
contributes thermal noise at the amplifier input and the value should be kept to the minimum in noise-sensitive
applications.

PHASE REVERSAL
The OPA322 op amps are designed to be immune to phase reversal when the input pins exceed the supply
voltages, therefore providing further in-system stability and predictability. Figure 31 shows the input voltage
exceeding the supply voltage without any phase reversal.

FEEDBACK CAPACITOR IMPROVES RESPONSE
For optimum settling time and stability with high-impedance feedback networks, it may be necessary to add a
feedback capacitor across the feedback resistor, RF, as shown in Figure 32. This capacitor compensates for the
zero created by the feedback network impedance and the OPA322 input capacitance (and any parasitic layout
capacitance). The effect becomes more significant with higher impedance networks.

NOTE: Where CIN is equal to the OPA322 input capacitance (approximately 9 pF) plus any parasitic layout capacitance.
Figure 32. Feedback Capacitor Improves Dynamic Performance
It is suggested that a variable capacitor be used for the feedback capacitor because input capacitance may vary
between op amps and layout capacitance is difficult to determine. For the circuit shown in Figure 32, the value of
the variable feedback capacitor should be chosen so that the input resistance times the input capacitance of the
OPA322 (typically 9 pF) plus the estimated parasitic layout capacitance equals the feedback capacitor times the
feedback resistor:
RIN × CIN = RF × CF
Where:
CIN is equal to the OPA322 input capacitance (sum of differential and common-mode) plus the layout
capacitance.
The capacitor value can be adjusted until optimum performance is obtained.
EMI SUSCEPTIBILITY AND INPUT FILTERING
Operational amplifiers vary in susceptibility to electromagnetic interference (EMI). If conducted EMI enters the
device, the dc offset observed at the amplifier output may shift from the nominal value while EMI is present. This
shift is a result of signal rectification associated with the internal semiconductor junctions. While all operational
amplifier pin functions can be affected by EMI, the input pins are likely to be the most susceptible. The OPA322
operational amplifier family incorporates an internal input low-pass filter that reduces the amplifier response to
EMI. Both common-mode and differential mode filtering are provided by the input filter. The filter is designed for a
cutoff frequency of approximately 580 MHz (–3 dB), with a roll-off of 20 dB per decade.
OUTPUT IMPEDANCE
The open-loop output impedance of the OPA322 common-source output stage is approximately 90 Ω. When the
op amp is connected with feedback, this value is reduced significantly by the loop gain. For each decade rise in
the closed-loop gain, the loop gain is reduced by the same amount, which results in a ten-fold increase in
effective output impedance. While the OPA322 output impedance remains very flat over a wide frequency range,
at higher frequencies the output impedance rises as the open-loop gain of the op amp drops. However, at these
frequencies the output also becomes capacitive as a result of parasitic capacitance. This characteristic, in turn,
prevents the output impedance from becoming too high, which can cause stability problems when driving large
capacitive loads. As mentioned previously, the OPA322 has excellent capacitive load drive capability for an op
amp with its bandwidth.

CAPACITIVE LOAD AND STABILITY
The OPA322 is designed to be used in applications where driving a capacitive load is required. As with all op
amps, there may be specific instances where the OPA322 can become unstable. The particular op amp circuit
configuration, layout, gain, and output loading are some of the factors to consider when establishing whether an
amplifier is stable in operation. An op amp in the unity-gain (+1 V/V) buffer configuration and driving a capacitive
load exhibits a greater tendency to become unstable than an amplifier operated at a higher noise gain. The
capacitive load, in conjunction with the op amp output resistance, creates a pole within the feedback loop that
degrades the phase margin. The degradation of the phase margin increases as the capacitive loading increases.
When operating in the unity-gain configuration, the OPA322 remains stable with a pure capacitive load up to
approximately 1 nF.
The equivalent series resistance (ESR) of some very large capacitors (CL > 1 µF) is sufficient to alter the phase
characteristics in the feedback loop such that the amplifier remains stable. Increasing the amplifier closed-loop
gain allows the amplifier to drive increasingly larger capacitance. This increased capability is evident when
observing the overshoot response of the amplifier at higher voltage gains, as shown in Figure 33. One technique
for increasing the capacitive load drive capability of the amplifier operating in unity gain is to insert a small
resistor (RS), typically 10 Ω to 20 Ω, in series with the output, as shown in Figure 34.
This resistor significantly reduces the overshoot and ringing associated with large capacitive loads. A possible
problem with this technique is that a voltage divider is created with the added series resistor and any resistor
connected in parallel with the capacitive load. The voltage divider introduces a gain error at the output that
reduces the output swing. The error contributed by the voltage divider, however, may be insignificant. For
instance, with a load resistance, RL = 10 kΩ and RS = 20 Ω, the gain error is only about 0.2%. However, when RL
is decreased to 600 Ω, which the OPA322 is able to drive, the error increases to 7.5%.

OVERLOAD RECOVERY TIME
Overload recovery time is the time required for the output of the amplifier to come out of saturation and recover
to the linear region. Overload recovery is particularly important in applications where small signals must be
amplified in the presence of large transients. Figure 35 and Figure 36 show the positive and negative overload
recovery times of the OPA322, respectively. In both cases, the time elapsed before the OPA322 comes out of
saturation is less than 100 ns. In addition, the symmetry between the positive and negative recovery times allows
excellent signal rectification without distortion of the output signal.

SHUTDOWN FUNCTION
The SHDN (enable) pin function of the OPAx322S is referenced to the negative supply voltage of the operational
amplifier. A logic level high enables the op amp. A valid logic high is defined as voltage [(V+) – 0.1 V], up to (V+),
applied to the SHDN pin. A valid logic low is defined as [(V–) + 0.1 V], down to (V–), applied to the enable pin.
The maximum allowed voltage applied to SHDN is 5.5 V with respect to the negative supply, independent of the
positive supply voltage. This pin should either be connected to a valid high or a low voltage or driven, and not left
as an open circuit.
The logic input is a high-impedance CMOS input. Dual op amp versions are independently controlled and quad
op amp versions are controlled in pairs with logic inputs. For battery-operated applications, this feature may be
used to greatly reduce the average current and extend battery life. The enable time is 10 µs for full shutdown of
all channels; disable time is 3 μs. When disabled, the output assumes a high-impedance state. This architecture
allows the OPAx322S to be operated as a gated amplifier (or to have the device output multiplexed onto a
common analog output bus). Shutdown time (tOFF) depends on loading conditions and increases with increased
load resistance. To ensure shutdown (disable) within a specific shutdown time, the specified 10-kΩ load to midsupply (VS / 2) is required. If using the OPAx322S without a load, the resulting turn-off time is significantly
increased.
GENERAL LAYOUT GUIDELINES
The OPA322 is a wideband amplifier. To realize the full operational performance of the device, follow good highfrequency printed circuit board (PCB) layout practices. The bypass capacitors must be connected between each
supply pin and ground as close to the device as possible. The bypass capacitor traces should be designed for
minimum inductance.
LEADLESS DFN PACKAGE
The OPA2322 uses the DFN style package (also known as SON), which is a QFN with contacts on only two
sides of the package bottom. This leadless package maximizes PCB space and offers enhanced thermal and
electrical characteristics through an exposed pad. One of the primary advantages of the DFN package is its low
height (0,8 mm).
DFN packages are physically small, and have a smaller routing area. Additionally, they offer improved thermal
performance, reduced electrical parasitics, and a pinout scheme that is consistent with other commonly-used
packages (such as SO and MSOP). The absence of external leads also eliminates bent-lead issues.

The DFN package can easily be mounted using standard PCB assembly techniques. See the application reports,
QFN/SON PCB Attachment (SLUA271) and Quad Flatpack No-Lead Logic Packages (SCBA017), both available
for download at www.ti.com. The exposed leadframe die pad on the bottom of the DFN package should be
connected to the most negative potential (V–). The dimension of the exposed thermal die pad is 2 mm ×
1,2 mm and is centered.
APPLICATION EXAMPLES
ACTIVE FILTER
The OPA322 is well-suited for active filter applications that require a wide bandwidth, fast slew rate, low-noise,
single-supply operational amplifier. Figure 37 shows a 500-kHz, second-order, low-pass filter using the multiplefeedback (MFB) topology. The components have been selected to provide a maximally-flat Butterworth response.
Beyond the cutoff frequency, roll-off is –40 dB/dec. The Butterworth response is ideal for applications that require
predictable gain characteristics, such as the anti-aliasing filter used in front of an ADC.
One point to observe when considering the MFB filter is that the output is inverted, relative to the input. If this
inversion is not required, or not desired, a noninverting output can be achieved through one of these options:
1. adding an inverting amplifier;
2. adding an additional second-order MFB stage; or
3. using a noninverting filter topology, such as the Sallen-Key (shown in Figure 38).
MFB and Sallen-Key, low-pass and high-pass filter synthesis is quickly accomplished using TI’s FilterPro™
program. This software is available as a free download at www.ti.com.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
