Overview
The OP490GP, produced by Analog Devices Inc., is a high-performance micropower quad operational amplifier. It is designed to operate from a single supply of 1.6 V to 36 V or from dual supplies of ±0.8 V to ±18 V. This versatility makes it suitable for a wide range of applications, including battery and solar-powered systems. The OP490GP features low supply current, high output drive, and low offset voltage, making it ideal for portable instruments and remote sensors.
