HIGH-LEVEL OUTPUT CURRENT  
The TLV2252 and TLV2254 are dual and  
quadruple low-voltage operational amplifiers from  
Texas Instruments. Both devices exhibit rail-to-rail  
output performance for increased dynamic range  
in single- or split-supply applications. The  
TLV225x family consumes only 34 µA of supply  
current per channel. This micropower operation  
makes them good choices for battery-powered  
applications. This family is fully characterized at  
3 V and 5 V and is optimized for low-voltage  
applications. The noise performance has been  
dramatically improved over previous generations  
of CMOS amplifiers. The TLV225x has a noise  
level of 19 nV/√Hz at 1kHz, four times lower than  
competitive micropower solutions.

The TLV225x, exhibiting high input impedance  
and low noise, are excellent for small-signal  
conditioning for high-impedance sources, such as  
piezoelectric transducers. Because of the micro-  
power 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). For precision  
applications, the TLV225xA family is available and has a maximum input offset voltage of 850 µV.
