GENERAL DESCRIPTION

The AD824 is a quad, FET input, single supply amplifier, featuring rail-to-rail outputs. The combination of FET inputs and rail-to-rail outputs makes the AD824 useful in a wide variety of low voltage applications where low input current is a primary consideration.

The AD824 is guaranteed to operate from a 3 V single supply up to ±15 V dual supplies. AD824AR-3V parametric performance at 3 V is fully guaranteed.
