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 950μV. This family is fully characterized at 5 V and ±5 V.
