The AD8031ANZ is a high speed, low power, rail-to-rail operational amplifier manufactured by Analog Devices. It has a gain-bandwidth product of 1.4 MHz and a slew rate of 8 V/µs. It is designed for use in 3V and 5V single-supply systems, and its operating temperature range is from -40°C to +85°C. It features low offset voltage (±1 mV) and input bias current (5 pA) as well as high common mode rejection ratio (110 dB). The output is short-circuit protected, and it can provide up to +/-4mA of output current. This part is ideal for high speed amplifiers, active filters, and signal conditioners.
