PRODUCT DESCRIPTION
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 IOUT ≤ 100 µA providing outstanding out put dynamic range.
Offset voltage of 800 µV max, offset voltage drift of 2 µV/°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/µs 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.
