AD823 is a dual-channel, 16MHz, Rail-to-Rail FET input amplifier from Analog Devices
The AD823 is a dual precision, 16 MHz JFET‑input operational amplifier that can operate from a single supply of 3 V to 36 V or dual supplies of ±1.5 V to ±18 V. It offers rail‑to‑rail output swing, high load‑drive capability, and low offset and noise performance, making it suitable for battery‑powered instrumentation, photodiode preamps, active filters, and high‑speed data‑acquisition systems.
The device is available in 8‑lead PDIP and SOIC packages, operates over an industrial temperature range (‑40 °C to +85 °C), and includes specifications for dynamic performance, noise, distortion, power consumption, and absolute maximum ratings.
