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.
Fabricated on ADI’s complementary bipolar process, the AD824
has a unique input stage that allows the input voltage to safely
extend beyond the negative supply and to the positive supply
without any phase inversion or latchup. The output voltage
swings to within 15 mV of the supplies. Capacitive loads to
350 pF can be handled without oscillation.
