AD823 is a single-supply, 16MHz, rail-to-rail FET input amplifier produced by Analog Devices, with a power supply voltage range from 3V to 36V, an output voltage range from ground to supply voltage, a 500pF output capacitance load capability, an output current of 15mA, an output voltage swing of 16MHz, a low distortion of -108dBc, a low noise of 16nV/√Hz, and no phase inversion, which can be applied to battery-powered precision instruments, photodiode preamplifiers, active filters, 12-bit to 16-bit data acquisition systems, and medical devices.
The AD823 is a dual, 16 MHz, rail‑to‑rail FET‑input operational amplifier that operates from a single supply of 3 V to 36 V or dual supplies of ±1.5 V to ±18 V. It offers single‑supply capability with an input voltage range extending below ground, high output drive, and low noise and distortion.
