GENERAL DESCRIPTION

The AD8502/AD8504 are low power, precision CMOS operational amplifiers featuring a maximum supply current of 1 μA. The AD8502/AD8504 have a maximum offset voltage of 3 mV and a typical input bias current of 1 pA operating rail-to-rail on both the input and output. The AD8502/AD8504 can operate from a single-supply voltage of +1.8 V to +5.5 V or a dual-supply voltage of ±0.9 V to ±2.75 V.
