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, the AD8500 is suitable for applications such as portable equipment, remote sensors, low power filters, threshold detectors, and current sensing.
The AD8500 is a micropower precision CMOS operational amplifier designed for battery‑powered portable applications. It operates from a single supply of 1.8 V to 5.5 V (or ±0.9 V to ±2.75 V) and features rail‑to‑rail input and output, a maximum supply current of 1 µA, and a typical offset voltage of 1 mV.
The device is supplied in a 5‑lead SC70 surface‑mount package and is specified over an industrial temperature range of –40 °C to +85 °C (extended to –40 °C to +125 °C). Key performance parameters such as input bias current, CMRR, and output swing are detailed in the specifications.
