AD8572ARZ

AD8572 is a dual channel, zero-drift, single-supply, rail-to-rail, input/output operational amplifier. Using Analog Devices, Inc., topology, this zero drift amplifier combine low cost with high accuracy (no external capacitors are required). Using a spread-spectrum, auto-zero technique, this device eliminate the intermodulation effects from interaction of the chopping function with the signal frequency in ac applications. Position and pressure sensors, medical equipment, and strain gauge amplifiers benefit greatly from nearly zero drift over their operating temperature range. Many more systems require the rail-to-rail input and output swings provided by the device. It is widely used in application such as temperature sensors, pressure sensors, precision current sensing, strain gauge amplifiers, medical instrumentation, thermocouple amplifiers etc.
