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.
The TLC227x/TLC227xA family are dual and quadruple rail‑to‑rail operational amplifiers offering low noise, low offset voltage, and high slew rate for precision and high‑speed applications. They are suitable for single‑supply or split‑supply designs and can interface directly with ADCs.
The devices are offered in multiple surface‑mount packages (D, J, N, PW) with detailed absolute‑maximum ratings, recommended operating conditions, and mechanical dimensions. The datasheet also includes an important notice on product warranties and usage rights.
