The TS461/2/4 is a family of low noise, low distortion, high dynamic range operational amplifiers that can operate with voltages as low as ±1.35V and to reach a minimum of ±2Vpp of output swing when supplied with ±2.5V.
The TS461, TS462 and TS464 are a family of rail‑to‑rail operational amplifiers designed for portable, battery‑supplied equipment. They offer low noise (4 nV/√Hz) and low distortion (0.003 %) and are suitable for sound cards, PDAs, CD players, recording equipment, multimedia and microphone preamplifiers.
Key specifications include an operating voltage range of 2.7 V to 10 V, a maximum supply voltage of 12 V, output swing up to +2.4 V at a 2.5 V supply, gain‑bandwidth product of 8.5‑12 MHz, and slew rate of 2.8‑4 V/µs. The devices are offered in several packages such as SOT‑23‑5L, SO‑8, mini‑SO‑8, TSSOP‑8, DIP‑8 and SO‑14.
