Datasheet Analog Devices AD823AR

Dual, 16 MHz, Rail-to-Rail
FET Input Amplifier
AD823 Data Sheet CONNECTION DIAGRAM An offset voltage of 800 µV maximum, an 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
Gigaohm. It provides 16 MHz, −3 dB bandwidth, −108 dB THD
@ 20 kHz, and a 22 V/µs 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. +VS 7 OUT2 +IN1 3 6 –IN2 –VS 4 5 +IN2 AD823 RL = 100kΩ

–1 OUTPUT (dB) 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 …
