The AD8500 is a low power, precision CMOS op amp featuring a maximum supply current of 1 μA. The AD8500 has a maximum offset voltage of 1 mV and a typical input bias current of 1 pA; it operates rail-to-rail on both the input and output. The AD8500 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. With its low power consumption, low input bias current, and rail-to-rail input and output, the AD8500 is ideally suited for a variety of basic applications, including portable equipment, remote sensors, low power filters, threshold detectors, and current sensing.
