The AD8661/AD8662/AD8664 is a low noise, precision 16V CMOS rail-to-rail operational amplifier that can operate from a single supply ranging from 5V to 16V.
The AD8661, AD8662, and AD8664 are low‑noise, precision, rail‑to‑rail operational amplifiers with single‑supply operation from 5 V to 16 V. They offer ultra‑low offset voltage (as low as 100 µV), extremely low input bias current (1 pA typical), and a wide bandwidth of 4 MHz, making them suitable for sensor, medical, audio, and photodiode applications.
These devices are offered in several compact packages, including 8‑lead SOIC, 8‑lead LFCSP, 8‑lead MSOP, 14‑lead SOIC, and 14‑lead TSSOP, with industrial temperature ranges from –40 °C to +125 °C (or –40 °C to +85 °C for the LFCSP version). The datasheet also includes an ordering guide and typical performance graphs.
