description
The TLV2341 operational amplifier has been specifically developed for low-voltage, single-supply applications
and is fully specified to operate over a voltage range of 2 V to 8 V. The device uses the Texas Instruments
silicon-gate LinCMOS technology to facilitate low-power, low-voltage operation and excellent offset-voltage
stability. LinCMOS technology also enables extremely high input impedance and low bias currents allowing
direct interface to high-impedance sources.
The TLV2341 offers a bias-select feature, which allows the device to be programmed with a wide range of
different supply currents and therefore different levels of ac performance. The supply current can be set at
17 µA, 250 µA, or 1.5 mA, which results in slew-rate specifications between 0.02 and 2.1 V/µs (at 3 V).
The TLV2341 operational amplifiers are especially well suited to single-supply applications and are fully
specified and characterized at 3-V and 5-V power supplies. This low-voltage single-supply operation combined
with low power consumption makes this device a good choice for remote, inaccessible, or portable
battery-powered applications. The common-mode input range includes the negative rail.
The device inputs and outputs are designed to withstand – 100-mA currents without sustaining latch-up. The
TLV2341 incorporates internal ESD-protection circuits that prevents functional failures at voltages up to
2000 V as tested under MIL-STD 883 C, Methods 3015.2; however, care should be exercised in handling these
devices as exposure to ESD may result in the degradation of the device parametric performance.

bias-select feature
The TLV2342 offers a bias-select feature that allows the user to select any one of three bias levels, depending
on the level of performance desired. The tradeoffs between bias levels involve ac performance and power
dissipation (see Table 1).

bias selection
Bias selection is achieved by connecting BIAS SELECT to one of three voltage levels (see Figure 1). For
medium-bias applications, it is recommended that the bias-select pin be connected to the midpoint between the
supply rails. This procedure is simple in split-supply applications since this point is ground. In single-supply
applications, the medium-bias mode necessitates using a voltage divider as indicated in Figure 1. The use of
large-value resistors in the voltage divider reduces the current drain of the divider from the supply line. However,
large-value resistors used in conjunction with a large-value capacitor require significant time to charge up to
the supply midpoint after the supply is switched on. A voltage other than the midpoint may be used if it is within
the voltages specified in the following table.

high-bias mode
In the high-bias mode, the TLV2341 series feature low offset voltage drift, high input impedance, and low noise.
Speed in this mode approaches that of BiFET devices but at only a fraction of the power dissipation.
medium-bias mode
The TLV2341 in the medium-bias mode features a low offset voltage drift, high input impedance, and low noise.
Speed in this mode is similar to general-purpose bipolar devices but power dissipation is only a fraction of that
consumed by bipolar devices.
low-bias mode
In the low-bias mode, the TLV2341 features low offset voltage drift, high input impedance, extremely low power
consumption, and high differential voltage gain.

single-supply versus split-supply test circuits
Because the TLV2341 is optimized for single-supply operation, circuit configurations used for the various tests
often present some inconvenience since the input signal, in many cases, must be offset from ground. This
inconvenience can be avoided by testing the device with split supplies and the output load tied to the negative
rail. A comparison of single-supply versus split-supply test circuits is shown below. The use of either circuit gives
the same result.

PARAMETER MEASUREMENT INFORMATION
input bias current
Because of the high input impedance of the TLV2341 operational amplifier, attempts to measure the input bias
current can result in erroneous readings. The bias current at normal ambient temperature is typically less than
1 pA, a value that is easily exceeded by leakages on the test socket. Two suggestions are offered to avoid
erroneous measurements:
•
•
Isolate the device from other potential leakage sources. Use a grounded shield around and between the
device inputs (see Figure 95). Leakages that would otherwise flow to the inputs are shunted away.
Compensate for the leakage of the test socket by actually performing an input bias current test (using a
picoammeter) with no device in the test socket. The actual input bias current can then be calculated by
subtracting the open-socket leakage readings from the readings obtained with a device in the test
socket.
Many automatic testers as well as some bench-top operational amplifier testers use the servo-loop
technique with a resistor in series with the device input to measure the input bias current (the voltage
drop across the series resistor is measured and the bias current is calculated). This method requires
that a device be inserted into the test socket to obtain a correct reading; therefore, an open-socket
reading is not feasible using this method.

low-level output voltage
To obtain low-level supply-voltage operation, some compromise is necessary in the input stage. This
compromise results in the device low-level output voltage being dependent on both the common-mode input
voltage level as well as the differential input voltage level. When attempting to correlate low-level output
readings with those quoted in the electrical specifications, these two conditions should be observed. If
conditions other than these are to be used, please refer to the Typical Characteristics section of this data sheet.
input offset voltage temperature coefficient
Erroneous readings often result from attempts to measure temperature coefficient of input offset voltage. This
parameter is actually a calculation using input offset voltage measurements obtained at two different
temperatures. When one (or both) of the temperatures is below freezing, moisture can collect on both the device
and the test socket. This moisture results in leakage and contact resistance which can cause erroneous input
offset voltage readings. The isolation techniques previously mentioned have no effect on the leakage since the
moisture also covers the isolation metal itself, thereby rendering it useless. These measurements should be
performed at temperatures above freezing to minimize error.
full-power response
Full-power response, the frequency above which the operational amplifier slew rate limits the output voltage
swing, is often specified two ways: full-linear response and full-peak response. The full-linear response is

generally measured by monitoring the distortion level of the output while increasing the frequency of a sinusoidal
input signal until the maximum frequency is found above which the output contains significant distortion. The
full-peak response is defined as the maximum output frequency, without regard to distortion, above which full
peak-to-peak output swing cannot be maintained.
Because there is no industry-wide accepted value for significant distortion, the full-peak response is specified
in this data sheet and is measured using the circuit of Figure 92. The initial setup involves the use of a sinusoidal
input to determine the maximum peak-to-peak output of the device (the amplitude of the sinusoidal wave is
increased until clipping occurs). The sinusoidal wave is then replaced with a square wave of the same
amplitude. The frequency is then increased until the maximum peak-to-peak output can no longer be maintained
(Figure 96). A square wave is used to allow a more accurate determination of the point at which the maximum
peak-to-peak output is reached.

test time
Inadequate test time is a frequent problem, especially when testing CMOS devices in a high-volume,
short-test-time environment. Internal capacitances are inherently higher in CMOS than in bipolar and BiFET
devices and require longer test times than their bipolar and BiFET counterparts. The problem becomes more
pronounced with reduced supply levels and lower temperatures.
APPLICATION INFORMATION
single-supply operation
While the TLV2341 performs well using dualpower supplies (also called balanced or split
supplies), the design is optimized for singlesupply operation. This includes an input commonmode voltage range that encompasses ground as
well as an output voltage range that pulls down to
ground. The supply voltage range extends down
to 2 V, thus allowing operation with supply levels
commonly available for TTL and HCMOS.
Many single-supply applications require that a
voltage be applied to one input to establish a
reference level that is above ground. This virtual
ground can be generated using two large
resistors, but a preferred technique is to use a
virtual-ground generator such as the TLE2426.
The TLE2426 supplies an accurate voltage equal
to VDD/2, while consuming very little power and is
suitable for supply voltages of greater than 4 V.

single-supply operation (continued)
The TLV2341 works well in conjunction with digital logic; however, when powering both linear devices and digital
logic from the same power supply, the following precautions are recommended:
•
•
Power the linear devices from separate bypassed supply lines (see Figure 98); otherwise, the linear
device supply rails can fluctuate due to voltage drops caused by high switching currents in the digital
logic.
Use proper bypass techniques to reduce the probability of noise-induced errors. Single capacitive
decoupling is often adequate; however, RC decoupling may be necessary in high-frequency
applications.

input offset voltage nulling
The TLV2341 offers external input offset null control. Nulling of the input offset voltage can be achieved by
adjusting a 25-kΩ potentiometer connected between the offset null terminals with the wiper connected as shown
in Figure 99. The amount of nulling range varies with the bias selection. In the high-bias mode, the nulling range
allows the maximum offset voltage specified to be trimmed to zero. In low-bias and medium-bias modes, total
nulling may not be possible.

bias selection
Bias selection is achieved by connecting the bias-select pin to one of the three voltage levels (see Figure 100).
For medium-bias applications, it is recommended that the bias-select pin be connected to the midpoint between
the supply rails. This is a simple procedure in split-supply applications, since this point is ground. In
single-supply applications, the medium-bias mode necessitates using a voltage divider as indicated. The use
of large-value resistors in the voltage divider reduces the current drain of the divider from the supply line.
However, large-value resistors used in conjunction with a large-value capacitor require significant time to charge
up to the supply midpoint after the supply is switched on. A voltage other than the midpoint may be used if it
is within the voltages specified in the following table.

input characteristics
The TLV2341 is specified with a minimum and a maximum input voltage that, if exceeded at either input, could
cause the device to malfunction. Exceeding this specified range is a common problem, especially in
single-supply operation. The lower the range limit includes the negative rail, while the upper range limit is
specified at VDD – 1 V at TA = 25°C and at VDD – 1.2 V at all other temperatures.
The use of the polysilicon-gate process and the careful input circuit design gives the TLV2341 good input offset
voltage drift characteristics relative to conventional metal-gate processes. Offset voltage drift in CMOS devices
is highly influenced by threshold voltage shifts caused by polarization of the phosphorus dopant implanted in
the oxide. Placing the phosphorus dopant in a conductor (such as a polysilicon gate) alleviates the polarization
problem, thus reducing threshold voltage shifts by more than an order of magnitude. The offset voltage drift with
time has been calculated to be typically 0.1 µV/month, including the first month of operation.
Because of the extremely high input impedance and resulting low bias-current requirements, the TLV2341 is
well suited for low-level signal processing; however, leakage currents on printed-circuit boards and sockets can
easily exceed bias-current requirements and cause a degradation in device performance. It is good practice
to include guard rings around inputs (similar to those of Figure 95 in the Parameter Measurement Information
section). These guards should be driven from a low-impedance source at the same voltage level as the
common-mode input (see Figure 101).
The inputs of any unused amplifiers should be tied to ground to avoid possible oscillation.

noise performance
The noise specifications in operational amplifiers circuits are greatly dependent on the current in the first-stage
differential amplifier. The low input bias-current requirements of the TLV2341 results in a very low noise current,
which is insignificant in most applications. This feature makes the device especially favorable over bipolar
devices when using values of circuit impedance greater than 50 kΩ, since bipolar devices exhibit greater noise
currents.
feedback
Operational amplifier circuits nearly always
employ feedback, and since feedback is the first
prerequisite for oscillation, caution is appropriate.
Most oscillation problems result from driving
capacitive loads and ignoring stray input
capacitance. A small-value capacitor connected
in parallel with the feedback resistor is an effective
remedy (see Figure 102). The value of this
capacitor is optimized empirically.

electrostatic-discharge protection
Figure 102. Compensation for Input Capacitance
The TLV2341 incorporates an internal electrostatic-discharge (ESD)-protection circuit that
prevents functional failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2. Care
should be exercised, however, when handling these devices as exposure to ESD may result in the degradation
of the device parametric performance. The protection circuit also causes the input bias currents to be
temperature dependent and have the characteristics of a reverse-biased diode.
latch-up
Because CMOS devices are susceptible to latch-up due to their inherent parasitic thyristors, the TLV2341 inputs
and output are designed to withstand – 100-mA surge currents without sustaining latch-up; however, techniques
should be used to reduce the chance of latch-up whenever possible. Internal protection diodes should not by

design be forward biased. Applied input and output voltage should not exceed the supply voltage by more that
300 mV. Care should be exercised when using capacitive coupling on pulse generators. Supply transients
should be shunted by the use of decoupling capacitors (0.1 µF typical) located across the supply rails as close
to the device as possible.
The current path established if latch-up occurs is usually between the positive supply rail and ground and can
be triggered by surges on the supply lines and/or voltages on either the output or inputs that exceed the supply
voltage. Once latch-up occurs, the current flow is limited only by the impedance of the power supply and the
forward resistance of the parasitic thyristor and usually results in the destruction of the device. The chance of
latch-up occurring increases with increasing temperature and supply voltages.
output characteristics
VDD
The output stage of the TLV2341 is designed to
sink and source relatively high amounts of current
(see Typical Characteristics). If the output is
subjected to a short-circuit condition, this
high-current capability can cause device damage
under certain conditions. Output current capability
increases with supply voltage.
Although the TLV2341 possesses excellent
high-level output voltage and current capability,
methods are available for boosting this capability
if needed. The simplest method involves the use
of a pullup resistor (RP) connected from the output
to the positive supply rail (see Figure 103). There
are two disadvantages to the use of this circuit.
First, the NMOS pulldown transistor N4 (see
equivalent schematic) must sink a comparatively
large amount of current. In this circuit, N4 behaves
like a linear resistor with an on resistance between
approximately 60 Ω and 180 Ω, depending on
how hard the operational amplifier input is driven.
With very low values of RP , a voltage offset from
0 V at the output occurs. Secondly, pullup resistor
RP acts as a drain load to N4 and the gain of the
operational amplifier is reduced at output voltage
levels where N5 is not supplying the output
current.

All operating characteristics of the TLV2341 are measured using a 20-pF load. The device drives higher
capacitive loads; however, as output load capacitance increases, the resulting response pole occurs at lower
frequencies thereby causing ringing, peaking, or even oscillation (see Figures 105, 106 and 107). In many
cases, adding some compensation in the form of a series resistor in the feedback loop alleviates the problem.
