The AD823 is a dual precision, 16 MHz, JFET input op amp that can operate from a single supply of +3.0 V to +36 V, or dual supplies of ±1.5 V to ±18 V. It has true single supply capability with an input voltage range extending below ground in single supply mode. Output voltage swing extends to within 50 mV of each rail for IOUT100 mA providing outstanding output dynamic range.

Offset voltage of 800 mV max, offset voltage drift of 2 mV/°C, input bias currents below 25 pA and low input voltage noise provide dc precision with source impedances up to a Gigohm. 16 MHz, 3 dB bandwidth, 108 dB THD @ 20 kHz and 22 V/ms slew rate are provided with a low supply current of 2.6 mA per amplifier. The AD823 drives up to 500 pF of direct capacitive load as a follower, and provides an output current of 15 mA, 0.5 V from the supply rails. This allows the amplifier to handle a wide range of load conditions.

This combination of ac and dc performance, plus the outstanding load drive capability results in an exceptionally versatile amplifier for applications such as A/D drivers, high-speed active filters, and other low voltage, high dynamic range systems.
