description
The TLV2231 is a single low-voltage operational amplifier available in the SOT -23 package. It of fers 2 MHz of
bandwidth and 1.6 V/µs of slew rate for applications requiring good ac performance. The device exhibits
rail-to-rail output performance for increased dynamic range in single or split supply applications. The TLV2231
is fully characterized at 3 V and 5 V and is optimized for low-voltage applications.
The TLV2231, exhibiting high input impedance and low noise, is excellent for small-signal conditioning of
high-impedance sources, such as piezoelectric transducers. Because of the micropower dissipation levels
combined with 3-V operation, these devices work well in hand-held monitoring and remote-sensing
applications. In addition, the rail-to-rail output feature with single- or split-supplies makes this family a great
choice when interfacing with analog-to-digital converters (ADCs). The device can also drive 600- loads for
telecom applications.
With a total area of 5.6mm2, the SOT -23 package only requires one-third the board space of the standard 8-pin
SOIC package. This ultra-small package allows designers to place single amplifiers very close to the signal
source, minimizing noise pick-up from long PCB traces. TI has also taken special care to provide a pinout that
is optimized for board layout (see Figure 1). Both inputs are separated by GND to prevent coupling or leakage
paths. The OUT and IN– terminals are on the same end of the board for providing negative feedback. Finally,
gain setting resistors and the decoupling capacitor are easily placed around the package.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only , and
functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may af fect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to VDD .
2. Differential voltages are at the noninverting input with respect to the inverting input. Excessive current flows when input is brought
below VDD 0.3 V.
3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum

APPLICATION INFORMATION
driving large capacitive loads
The TLV2231 is designed to drive larger capacitive loads than most CMOS operational amplifiers. Figure 50
through Figure 55 illustrate its ability to drive loads greater than 100 pF while maintaining good gain and phase
margins (Rnull = 0).
A small series resistor (Rnull) at the output of the device (see Figure 56) improves the gain and phase margins
when driving large capacitive loads. Figure 50 through Figure 53 show the effects of adding series resistances
of 50 , 100 , 500 , and 1000 . The addition of this series resistor has two effects: the first effect is that
it adds a zero to the transfer function and the second effect is that it reduces the frequency of the pole associated
with the output load in the transfer function.
The zero introduced to the transfer function is equal to the series resistance times the load capacitance. To
calculate the approximate improvement in phase margin, equation 1 can be used.

Macromodel information provided was derived using Microsim Parts, the model generation software used
with Microsim PSpice. The Boyle macromodel (see Note 6) and subcircuit in Figure 57 are generated using
the TLV2231 typical electrical and operating characteristics at TA = 25°C. Using this information, output
simulations of the following key parameters can be generated to a tolerance of 20% (in most cases):
D
Maximum positive output voltage swing
D
Maximum negative output voltage swing

Quiescent power dissipation
