The TLC2262 and TLC2264 are dual and  
60  
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  
TLC226x family offers a compromise between the  
micropower TLC225x and the ac performance of  
the TLC227x. It has low supply current for  
battery-powered applications, while still having  
adequate ac performance for applications that  
demand it. The noise performance has been  
dramatically improved over previous generations  
of CMOS amplifiers. Figure 1 depicts the low level  
of noise voltage for this CMOS amplifier, which  
has only 200 µA (typ) of supply current per  
amplifier.

The TLC226x, 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, 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 TLC226xA  
family is available and has a maximum input offset voltage of 950 µV. This family is fully characterized at 5 V  
and 5 V.  
The TLC2262/4 also makes great upgrades to the TLC27M2/L4 or TS27M2/L4 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. 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.
