NE/SE531 is a high gain, high stability operational amplifier from Philips Semiconductors. It has a unity gain bandwidth of 35V/µs and is the ideal solution for all slew rate limited operational amplifiers.
The NE/SE531 is a fast‑slewing, high‑performance operational amplifier that maintains DC performance comparable to the best general‑purpose types while delivering superior large‑signal AC performance. Its unique input stage provides large‑signal response nearly identical to its small‑signal response, and it is compensated with a single capacitor for negligible overshoot.
The device is offered in 8‑pin DIP and CERDIP packages covering temperature ranges from –55 °C to +125 °C. Typical applications include high‑speed inverters, voltage‑followers, precision rectifiers, and waveform generators, with detailed performance graphs and test circuits provided in the document.
