description

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.  
The TLV2252/4 also make great upgrades to the TLV2322/4 in standard designs. They offer increased output  
dynamic range, lower noise voltage, and lower input offset voltage. This enhanced feature set allows them to  
be used in a wider range of applications. For applications that require higher output drive and wider input voltage  
range, see the TLV2432 and TLV2442 devices. If your design requires single amplifiers, please see the  
TLV2211/21/31 family. These devices are single rail-to-rail operational amplifiers in the SOT-23 package. Their  
small size and low power consumption, make them ideal for high density, battery-powered equipment.
