The OP271 is a high-speed, low-power operational amplifier from Analog Devices with excellent performance, fast settling time and high gain bandwidth, making it suitable for a wide range of high-performance applications.
The OP271 is a monolithic dual operational amplifier offering excellent speed (8.5 V/µs typical) and fast settling (2 µs to 0.01%). It provides a gain‑bandwidth product of 5 MHz, low input offset voltage (≤200 µV), high CMRR (≥106 dB) and low input bias current (<20 nA), making it suitable for precision instrumentation, active filters, and high‑speed buffers.
The device uses the standard 8‑pin dual op‑amp pinout and is pin‑compatible with TL072, TL082, LF412, and 1458/1558 parts. It is available in various packages (SOIC, DIP, hermetic) and includes ESD protection. Absolute maximum ratings include a supply voltage of +18 V and a differential input voltage limit of ±1.0 V.
