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. Functional operation of the device at these conditions, or beyond the specified
operating conditions, is not implied.
Input terminals are not diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails
should be current-limited to 10mA or less.

APPLICATION INFORMATION
The OPA348 series op amps are unity-gain stable
and suitable for a wide range of general-purpose
applications.
The OPA348 series features wide bandwidth and
unity-gain stability with rail-to-rail input and output for
increased dynamic range. Figure 19 shows the input
and output waveforms for the OPA348 in unity-gain
configuration. Operation is from a single +5V supply
with a 100kΩ load connected to VS/2. The input is a
5VPP sinusoid. Output voltage is approximately
4.98VPP.
Power-supply pins should be bypassed with 0.01μF
ceramic capacitors.
G = +1V/V, VS = +5V
Output (Inverted on Scope)
The input common-mode voltage range of the
OPA348 series extends 200mV beyond the supply
rails. This is achieved with a complementary input
stage—an N-channel input differential pair in parallel
with a P-channel differential pair. The N-channel pair
is active for input voltages close to the positive rail,
typically (V+) – 1.2V to 300mV above the positive
supply, while the P-channel pair is on for inputs from
300mV below the negative supply to approximately
(V+) – 1.4V. There is a small transition region,
typically (V+) – 1.4V to (V+) – 1.2V, in which both
pairs are on. This 200mV transition region, shown in
Figure 20, can vary ±300mV with process variation.
Thus, the transition region (both stages on) can range
from (V+) – 1.7V to (V+) – 1.5V on the low end, up to
(V+) – 1.1V to (V+) – 0.9V on the high end. Within the
200mV transition region PSRR, CMRR, offset
voltage, offset drift, and THD may be degraded
compared to operation outside this region.

OPERATING VOLTAGE
The OPA348 series op amps are fully specified and
tested from +2.5V to +5.5V. However, supply voltage
may range from +2.1V to +5.5V. Parameters are
tested over the specified supply range—a unique
feature of the OPA348 series. In addition, all
temperature specifications apply from –40°C to
+125°C. Most behavior remains virtually unchanged
throughout the full operating voltage range.
Parameters that vary significantly with operating
voltages or temperature are shown in the Typical
Characteristics.

RAIL-TO-RAIL INPUT
RAIL-TO-RAIL OUTPUT
The input common-mode range extends from (V–) –
0.2V to (V+) + 0.2V. For normal operation, inputs
should be limited to this range. The absolute
maximum input voltage is 500mV beyond the
supplies. Inputs greater than the input common-mode
range but less than the maximum input voltage, while
not valid, will not cause any damage to the op amp.
Unlike some other op amps, if input current is limited
the inputs may go beyond the power supplies without
phase inversion, as shown in Figure 21.
A class AB output stage with common-source
transistors is used to achieve rail-to-rail output. This
output stage is capable of driving 5kΩ loads
connected to any potential between V+ and ground.
For light resistive loads (> 100kΩ), the output voltage
can typically swing to within 18mV from supply rail.
With moderate resistive loads (10kΩ to 50kΩ), the
output voltage can typically swing to within 100mV of
the supply rails while maintaining high open-loop gain
(see the typical characteristic Output Voltage Swing
vs Output Current, Figure 6).

Figure 21. OPA348—No Phase Inversion with
Inputs Greater than the Power-Supply Voltage
Normally, input currents are 0.5pA. However, large
inputs (greater than 500mV beyond the supply rails)
can cause excessive current to flow in or out of the
input pins. Therefore, as well as keeping the input
voltage below the maximum rating, it is also important
to limit the input current to less than 10mA. This is
easily accomplished with an input voltage resistor, as
shown in Figure 22.
CAPACITIVE LOAD AND STABILITY
The OPA348 in a unity-gain configuration can directly
drive up to 250pF pure capacitive load. Increasing the
gain enhances the amplifier’s ability to drive greater
capacitive loads (see the typical characteristic SmallSignal Overshoot vs Capacitive Load, Figure 13). In
unity-gain configurations, capacitive load drive can be
improved by inserting a small (10Ω to 20Ω) resistor,
RS, in series with the output, as shown in Figure 23.
This significantly reduces ringing while maintaining
DC performance for purely capacitive loads.
However, if there is a resistive load in parallel with
the capacitive load, a voltage divider is created,
introducing a Direct Current (DC) error at the output
and slightly reducing the output swing. The error
introduced is proportional to the ratio RS/RL, and is
generally negligible.

In unity-gain inverter configuration, phase margin can
be reduced by the reaction between the capacitance
at the op amp input, and the gain setting resistors,
thus degrading capacitive load drive. Best
performance is achieved by using small valued
resistors. For example, when driving a 500pF load,
reducing the resistor values from 100kΩ to 5kΩ
decreases overshoot from 55% to 13% (see the
typical characteristic Small-Signal Overshoot vs Load
Capacitance, Figure 13). However, when large valued
resistors cannot be avoided, a small (4pF to 6pF)
capacitor, CFB, can be inserted in the feedback, as
shown in Figure 24. This significantly reduces
overshoot by compensating the effect of capacitance,
CIN, which includes the amplifier's input capacitance
and PC board parasitic capacitance.

DRIVING A/D CONVERTERS
The OPA348 series op amps are optimized for driving
medium-speed sampling Analog-to-Digital Converters
(ADCs). The OPA348 op amps buffer the ADCs input
capacitance and resulting charge injection while
providing signal gain.
The OPA348 in a basic noninverting configuration
driving the ADS7822, see Figure 25. The ADS7822 is
a 12-bit, microPOWER sampling converter in the
MSOP-8 package. When used with the low-power,
miniature packages of the OPA348, the combination
is ideal for space-limited, low-power applications. In
this configuration, an RC network at the ADC’s input
can be used to provide for anti-aliasing filter and
charge injection current.
The OPA348 in noninverting configuration driving
ADS7822 limited, low-power applications. In this
configuration, an RC network at the ADC’s input can
be used to provide for antialiasing filter and charge
injection current. See Figure 26 for the OPA2348
driving an ADS7822 in a speech bandpass filtered
data acquisition system. This small, low-cost solution
provides the necessary amplification and signal
conditioning to interface directly with an electret
microphone. This circuit will operate with VS = 2.7V to
5V with less than 250μA typical quiescent current.
