Description

The AD896JR 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 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 µA providing outstanding output dynamic range. The AD896JR has an offset voltage of 800 µV max, offset voltage drift of 2 µV/°C, input bias currents below 25 pA, and low input voltage noise providing DC precision with source impedances up to a gigohm. With a bandwidth of 16 MHz, –3 dB, and –108 dB THD @ 20 kHz, the AD896JR offers excellent AC performance with a low supply current of 2.6 mA per amplifier. It can drive 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, allowing it to handle a wide range of load conditions.
