TLC227x, TLC227xA: Advanced LinCMOS Rail-to-Rail Operational Amplifiers  
The TLC227x also make great upgrades to the  
TLC27x 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 the design requires single amplifiers, see the  
TLV2211, TLV2221 and TLV2231 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.

3 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 family of devices, 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
