AD824 is a low power, single supply, full range output operational amplifier from Analog Devices. It features low input bias current, wide input voltage range, low supply current and wide bandwidth. It is widely used in photo diode preamplifier, battery powered instrumentation, power supply control and protection, medical instrumentation, remote sensors, low voltage strain gage amplifiers and DAC output amplifier etc.
The AD824 is a quad, FET‑input operational amplifier designed for low‑voltage applications. It operates from a single 3 V supply up to 30 V, or ±15 V dual supplies, and provides rail‑to‑rail output swing within 15 mV of the supply rails. Key features include a very low input bias current of 2 pA, offset voltage as low as 0.1 mV, 2 MHz bandwidth, and a 2 V/µs slew rate.
Typical applications cover photo‑diode preamplifiers, battery‑powered instrumentation, medical devices, and precision sample‑and‑hold circuits. The device is offered in 14‑lead and 16‑lead SOIC packages suitable for surface‑mount designs.
