description

The TL V2731 is a single low-voltage operational amplifier available in the SOT-23 package. It offers 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 TL V2731
is fully characterized at 3 V and 5 V and is optimized for low-voltage applications.

The TLV2731, 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-Ω loads for
telecom applications.

With a total area of 5.6mm
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.

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 affect device reliability.

NOTES: 1. All voltage values, except differential voltages, are with respect to V

2. Differential voltages are at the noninverting input with respect to the inverting input. Excessive current flows when input is brought
below V

3. The output may be shorted to either supply. Temperature and /or supply voltages must be limited to ensure that the maximum
