MAX492CSA

MAX492CSA Description

The MAX492CSA from Analog Devices Inc./Maxim Integrated is a dual-channel general-purpose operational amplifier designed for precision analog applications. Packaged in an 8-SOIC surface-mount configuration, this IC operates over a 2.7V to 6V supply range, making it suitable for low-voltage systems. With a 500 kHz gain bandwidth product and a 0.2V/µs slew rate, it balances performance and power efficiency, drawing just 150µA per channel. The device features low input bias current (25 nA) and 200 µV input offset voltage, ensuring accuracy in signal conditioning. Although marked as obsolete, it remains relevant for legacy designs requiring stable, low-power op-amps.
