AD824 is a single supply operational amplifier with features of low power and wide range. It is suitable for applications such as photo diode preamplifier, battery powered instrumentation, power supply control and protection, medical instrumentation, remote sensors, low voltage strain gage amplifiers, and DAC output amplifier.
The AD824 is a quad, FET‑input operational amplifier designed for low‑voltage, low‑power applications such as battery‑powered instrumentation, medical devices, and photo‑diode preamplifiers. It features single‑supply operation from 3 V to 30 V, rail‑to‑rail output swing, very low input bias current, and a 2 MHz bandwidth.
The datasheet provides detailed electrical specifications, pin configurations for 14‑lead and 16‑lead SOIC packages, absolute maximum ratings, ordering information, and mechanical outline dimensions. Typical performance graphs illustrate gain‑bandwidth, noise density, and distortion characteristics.
