The AD820ARZ is a precision, low power FET input Operational Amplifier that can operate from a single supply of 5 to 36V or dual supplies of ±2.5 to ±18V. It has true single-supply capability, with an input voltage range extending below the negative rail, allowing this to accommodate input signals below ground in the 1-supply mode. Output voltage swing extends to within 10mV of each rail, providing the maximum output dynamic range. This drives up to 350pF of direct capacitive load and provides a minimum output current of 15mA. This 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.
