应用功能： Single Supply, Rail-to-RailLow Power FET-Input Op Amp The AD822 is a dual precision, low power FET input opamp that can operate from a single supply of +3.0 V to 36 V,or dual supplies of ±1.5 V to ±18 V. It has true single supplycapability with an inputvoltage range extending below thenegative rail, allowing theAD822toaccommodateinputsignalsbelowgroundinthesinglesupplymode.Outputvoltageswingextends to within 10 mV of eachrailprovidingthemaximumoutput dynamic range.
