The TLC2272 and TLC2274 are dual and quad 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 TLC2272 and TLC2274 are dual and quadruple operational amplifiers from Texas Instruments. They provide rail‑to‑rail output, low noise (9 nV/√Hz), low input offset voltage (950 µV max at 25 °C) and operate from single‑ or split‑supply voltages. The devices are offered in a variety of packages, including ceramic LCC, DIP, plastic DIP, TSSOP, and flat‑pack, covering temperature ranges from –55 °C to 125 °C.
The datasheet lists absolute‑maximum ratings, electrical characteristics such as supply voltage range (±2.2 V to ±8 V), slew rate (3.6 V/µs), gain‑bandwidth product (2.2 MHz), and typical performance parameters. Package thermal impedance and recommended operating conditions are also provided for each package type.
