DESCRIPTION  
The TLC2272 and TLC2274 are dual and 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 TLC227x family offers 2 MHz of  
bandwidth and 3 V/μs of slew rate for higher speed  
applications. These devices offer comparable ac  
performance while having better noise, input offset  
voltage, and power dissipation than existing CMOS  
operational amplifiers. The TLC227x has a noise  
voltage of 9 nV/Hz, two times lower than competitive  
solutions.

The TLC227x, 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, 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 TLC227xA family is  
available with a maximum input offset voltage of 950  
μV. This family is fully characterized at 5 V and ±5 V.

The TLC2272/4 also makes great upgrades to the  
TLC272/4 or TS272/4 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.
