APPLICATIONS Photo diode preamplifier Battery powered instrumentation Power supply control and protection Medical instrumentation Remote sensors Low voltage strain gage amplifiers DAC output amplifier GENERAL DESCRIPTION
The AD824 is a quad, FET input, single supply amplifier, The FET input combined with laser trimming provides an input featuring rail-to-rail outputs. The combination of FET inputs that has extremely low bias currents with guaranteed offsets and rail-to-rail outputs makes the AD824 useful in a wide below 1 mV. This enables high accuracy designs even with high variety of low voltage applications where low input current is source impedances. Precision is combined with low noise, a primary consideration. making the AD824 ideal for use in battery powered medical The AD824 is guaranteed to operate from a 3 V single supply equipment. up to ±15 V dual supplies. AD824AR-3V parametric Applications for the AD824 include portable medical performance at 3 V is fully guaranteed. equipment, photo diode preamplifiers, and high impedance Fabricated on Analog Devices, Inc., complementary bipolar transducer amplifiers. process, the AD824 has a unique input stage that al ows the The ability of the output to swing rail-to-rail enables designers input voltage to safely extend beyond the negative supply and to build multistage filters in single supply systems and maintain to the positive supply without any phase inversion or latch-up. high signal-to-noise ratios. The output voltage swings to within 15 mV of the supplies. The AD824 is specified over the extended industrial (−40°C to Capacitive loads to 350 pF can be handled without oscil ation. +85°C) temperature range and is available in narrow 14-lead SOIC package.
