AD8602AR

AD8602AR Description

The AD8602AR from Analog Devices Inc. is a high-performance, CMOS-based dual operational amplifier in an 8-SOIC package, part of the DigiTrim® series. Designed for precision applications, it operates over a 2.7V to 5.5V supply range, making it suitable for low-voltage systems. With a Gain Bandwidth Product (GBW) of 8.4 MHz and a slew rate of 6V/µs, it delivers fast signal processing while maintaining accuracy. The device features ultra-low input bias current (0.2 pA) and low input offset voltage (80 µV), ensuring minimal error in sensitive circuits. Despite its obsolete status, it remains a reliable choice for legacy designs requiring low power consumption (750µA per channel) and high output current (50 mA per channel).
