AD823 Amplifier Datasheet
Product Overview 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 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 50 mV of each rail for IOUT ≤ 100 μ A, providing outstanding output dynamic range. An offset voltage of 800 μ V maximum, an offset voltage drift of 2 μ V/ ° C, input bias currents below 25 pA, and low input voltage noise provide dc precision with source impedances up to a Gigaohm. It provides 16 MHz, − 3 dB bandwidth, − 108 dB THD @ 20 kHz, and a 22 V/ μ s slew rate 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 blog will introduce AD ...
