AD746 is a dual version of the AD744 BiFET op amp, offering excellent dc characteristics, rapid settling times, high output swing, and low distortion
The AD746 combines two AD744 BiFET op‑amps on a single chip, offering excellent DC precision, rapid settling (500 ns to 0.01 %), high slew rate, and wide bandwidth. It is internally compensated for unity‑gain stability and is available in three 8‑pin packages: Plastic Mini‑DIP, hermetic Cerdip, and surface‑mount SOIC.
Typical applications include buffer amplifiers for 12‑ and 14‑bit DACs, precision ADC input stages, wide‑bandwidth pre‑amplifiers, and low‑distortion audio circuits. The device includes ESD protection and recommended power‑supply bypassing for high‑frequency performance.
| Input Offset Voltage (typical) | 0.3 mV |
|---|---|
| Settling Time to 0.01 % | 500 ns |
| Total Harmonic Distortion (1 kHz) | 0.0001 % |
| Power Supply Rated Performance | ±15 V |
The AD746 settles to 0.01 % in 500 ns for a 10 V step.
The typical THD is 0.0001 % at 1 kHz.
The AD746 is offered in 8‑pin Plastic Mini‑DIP, Cerdip, and Surface‑Mount (SOIC) packages.
