AD820ARZ-REEL7

AD820 is a single supply, low power, FET input opamp. It has true single-supply capability, with an input voltage range extending below the negative rail, allowing the opamp to accommodate input signals below ground in the single-supply mode. Output voltage swing extends to within 10mV of each rail, providing maximum output dynamic range. It allows the amplifier to handle a wide range of load conditions. This combination of ac and dc performance, plus the outstanding load drive capability, results in an exceptionally versatile amplifier for the single-supply user. It is mainly used in application such as battery-powered precision instrumentation, photodiode preamps, active filters, 12bit to 14bit data acquisition systems, medical instrumentation, low power references and regulators etc.
