quadruple operational amplifiers from Texas  
Instruments. Both devices exhibit rail-to-rail  
output performance for increased dynamic range  
in single- or split-supply applications. The  
TLC225x family consumes only 35 µA of supply  
current per channel. This micropower operation  
makes them good choices for battery-powered  
applications. The noise performance has been  
dramatically improved over previous generations  
of CMOS amplifiers. Looking at Figure 1, the  
TLC225x has a noise level of 19 nV/Hz at 1kHz;  
four times lower than competitive micropower  
solutions.

The TLC225x amplifiers, exhibiting high input  
impedance and low noise, are excellent for  
small-signal conditioning for high-impedance  
sources, such as piezoelectric transducers.  
Because of the micropower dissipation levels,  
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 TLC225xA family is available and has a maximum input offset voltage of 850 µV. This  
family is fully characterized at 5 V and 5 V.
