AD824:  Single Supply, Rail-to-Rail Low Power, FET-Input Op Amp

Product 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 volt dual supplies.

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 millivolts of the supplies. Capacitive loads to 350 pF can be handled without oscillation.

The FET input combined with laser trimming provides an input that has extremely low bias currents with guaranteed offsets below 300 µV. This enables high accuracy designs even with high source impedances. Precision is combined with low noise, making the AD824 ideal for use in battery powered medical equipment.

Applications for the AD824 include portable medical equipment, photo diode preamplifiers and high impedance transducer amplifiers.

The ability of the output to swing rail-to-rail enables designers to build multistage filters in single supply systems and maintain high signal-to-noise ratios.

The AD824 is specified over the extended industrial (-40°C to +85°C) temperature range and is available in 14-pin DIP and narrow 14-pin and 16-pin SO packages.

    • Single Supply Operation: 3 V to 30 V
    • Very Low Input Bias Current: 2 pA
    • Wide Input Voltage Range
    • Rail-to-Rail Output Swing
    • Low Supply Current: 500 µA/Amp
    • Wide Bandwidth: 2 MHz
    • Slew Rate: 2 V/µs
    • No Phase Reversal
