description

The TLV2731 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 TLV2731

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 5.6mm2, 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.
