AD823ARZ Description


The AD823 is a 16 MHz dual precision JFET input op-amp that may be powered by a single 3.0 V to 36 V supply or two 1.5 V to 18 V supplies. In single-supply mode, it features a real single-supply input voltage range that extends below ground. For IOUT 100 A, the output voltage swing is within 50 mV of each rail, resulting in a wide output dynamic range.


With source impedances up to a Gigaohm, dc precision is provided by an offset voltage of 800V maximum, an offset voltage drift of 2V/°C, input bias currents below 25 pA, and low input voltage noise. With a low supply current of 2.6 mA per amplifier, it provides 16 MHz, 3 dB bandwidth, 108 dB THD @ 20 kHz, and a 22 V/s slew rate. As a follower, the AD823 drives up to 500 pF of direct capacitive load and generates a 15 mA output current at 0.5 V from the supply rails. This enables the amplifier to cope with a variety of load circumstances.
