The AD746 is a dual operational amplifier, consisting of two AD744 BiFET op amps on a single chip.
The AD746 is a dual BIFET operational amplifier offering fast 500 ns settling to 0.01 % for a 10 V step, a 75 V/µs slew rate, and ultra‑low total harmonic distortion of 0.0001 %. It provides high DC precision with offset voltage as low as 0.5 mV (AD746B) and open‑loop gain of at least 175 V/mV.
Available in three 8‑pin packages—Plastic Mini‑DIP, hermetic Cerdip, and Surface‑Mount—the device supports a wide supply range (+4.5 V to +18 V) and can be processed to MIL‑STD‑883B for military applications. Detailed electrical characteristics, absolute maximum ratings, and typical performance curves are provided for design reference.
