Analog Devices ADHV4702-1 Operational Amplifier | DigiKey Daily

Analog Devices offers their ADHV4702-1, which is a high voltage, unity-gain stable precision operational amplifier. It offers high input impedance with low input bias current, low input offset voltage, low drift, and low noise for accuracy demanding applications. It features a wide range of operating voltages, including up to 220 volts. For precision performance, this op-amp has a 170 dB open-loop gain and a 160 dB common-mode rejection ratio. It offers high voltage input common-mode swing as well as high voltage output swing, enabling precision high voltage use cases such as high-side current sensing. This device is also ideally suited for forcing a voltage in precision bias and control applications. Other applications include piezotransducers, automated test equipment, LiDAR, and more.
