Analog Devices AD745 Ultralow Noise High Speed BiFET Op Amp Datasheet
The AD745 combines the low voltage noise of bipolar op‑amps with the low input current of FET devices. It offers 2.9 nV/√Hz noise at 10 kHz, 0.38 µV p‑p low‑frequency noise, and a 0.5 mV maximum offset voltage, making it suitable for precision low‑noise applications.
Typical applications include sonar, photodiode amplifiers, accelerometers, hydrophones, and high‑performance audio. The device is supplied in a 16‑lead SOIC package (AD745J/K) and is available in tape‑and‑reel form.
