STMicroelectronics TS971/TS972/TS974 Operational Amplifier Datasheet
The TS97x family of operational amplifiers from STMicroelectronics offers rail‑to‑rail output swing, ultra‑low noise (4 nV/√Hz) and very low distortion (0.003 %). These features make the devices suitable for portable, battery‑powered equipment and audio pre‑amplification. The three variants – TS971, TS972 and TS974 – are available in several compact packages such as SOT23‑5, QFN8, DIP8, TSSOP8 and TSSOP14.
The datasheet details absolute maximum ratings, electrical characteristics (gain‑bandwidth product up to 12 MHz, slew rate 4 V/µs, supply current 2.8 mA), and mechanical dimensions for each package. Order codes, temperature ranges, and revision history are also included.
