View Datasheet Manufacturer Site View Pricing & Stock

The AD823A is a dual precision, 17 MHz, JFET input op amp manufactured in the extra fast complementary bipolar (XFCB) process. The AD823A can operate from a single supply of 3 V to 36 V or from 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 20 mV of each rail for IOUT ≤ 100 μA, providing outstanding output dynamic range. It also has a linear output current of 40 mA, 0.5 V from the supply rails.An offset voltage of 700 μV maximum, an offset voltage drift of 1 μV/°C, and typical input bias currents of 0.3 pA provide dc precision with source impedances up to 1 GΩ. The AD823A provides 17 MHz, −3 dB bandwidth, and a 30 V/μs slew rate with a low supply current of only 2.6 mA per amplifier. It also provides low input voltage noise of 14 nV/√Hz and −108 dB SFDR at 20 kHz. The AD823A has low input capacitances (0.6 pF differential and 1.3 pF common mode) and drives more than 500 pF of direct capacitive load as a follower. This lets the amplifier 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
