The AD824 is a low voltage single supply amplifier from Analog Devices with ultra low input current and rail-to-rail output. It is suitable for a wide range of low voltage applications.
The AD824 is a four‑channel operational amplifier designed for low‑voltage, low‑bias‑current applications. It operates from a single 3 V supply up to ±15 V dual supplies and provides rail‑to‑rail output swing, making it suitable for battery‑powered instrumentation, medical devices, and photo‑diode preamplifiers.
The datasheet details electrical specifications, pin configurations for 14‑lead and 16‑lead SOIC packages, absolute maximum ratings, and typical performance graphs such as gain‑bandwidth, slew rate, and noise. Sample circuits illustrate headphone drivers, bridge drivers, and precision sample‑and‑hold applications.
