DESCRIPTION

· The AD823 is a dual precision, 16 MHz, JFET input operational amplifier.

· Operates from a single supply of 3.0 V to 36 V or dual supplies of ±1.5 V to ±18 V.

· Features true single-supply capability with an input voltage range extending below ground.

· Output voltage swing extends to within 50 mV of each rail for IOUT ≤ 100 µA.

· Provides 16 MHz, -3 dB bandwidth, -108 dB THD @ 20 kHz, and a 22 V/µs slew rate.

· Low supply current of 2.6 mA per amplifier.

· Drives up to 500 pF of direct capacitive load and provides an output current of 15 mA.

FEATURES

· Single-supply operation with output swings rail-to-rail.

· Input voltage range extends below ground.

· High load drive with capacitive load drive of 500 pF, G = +1.
