Product Details
●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. 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 latch-up. The output voltage swings to within 15 mV 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 1 mV. 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 narrow 14-lead SOIC package.
