description  
The TLV2721 is a single low-voltage operational amplifier available in the SOT-23 package. It offers a  
compromise between the ac performance and output drive of the TLV2731 and the micropower TLV2711.  
It consumes only 150 µA (max) of supply current and is ideal for battery-powered applications. The device  
exhibits rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The  
TLV2721 is fully characterized at 3 V and 5 V and is optimized for low-voltage applications.  
The TLV2721, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for  
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).

With a total area of 5.6mm , 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.
