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.
The AD8500 is a low‑power, precision CMOS operational amplifier featuring a maximum supply current of about 1 µA, rail‑to‑rail input and output, and a maximum offset voltage of 1 mV. Its low input bias current (10 pA typical) and rail‑to‑rail operation make it suitable for battery‑powered portable equipment such as ECGs, pulse monitors, and smoke detectors.
The datasheet lists detailed electrical characteristics, absolute maximum ratings, thermal resistance, and typical performance curves. It also includes pin configuration, ordering information for the 5‑lead SC70 (KS‑5) package, and recommended applications for low‑power filters, threshold detectors, and current sensing circuits.
