AD823AN

** AD823AN Description **

The AD823AN is a dual precision, 17 MHz, JFET input op-amp manufactured in the extra fast complementary bipolar (XFCB) process. This device 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 the 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.
