description  
The TLV2221 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 TLV2231 and the micropower TLV2211.  
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  
TLV2221 is fully characterized at 3 V and 5 V and is optimized for low-voltage applications.  
The TLV2221, 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. 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 INterminals are on the same end of the board to provide negative feedback. Finally, gain  
setting resistors and decoupling capacitor are easily placed around the package.
