MAX494CSD

MAX494CSD Description

The MAX494CSD from Analog Devices Inc./Maxim Integrated is a general-purpose quad operational amplifier designed for precision analog applications. Housed in a 14-pin SOIC package, this IC operates over a 2.7V to 6V supply range, making it suitable for low-voltage systems. With four independent op-amps in a single package, it offers space-efficient solutions for multi-channel designs. The device features a 500 kHz gain bandwidth product, 0.2V/µs slew rate, and low input bias current (25 nA), ensuring stable performance in signal conditioning and filtering applications. Its low supply current (150µA per channel) and 30 mA output drive capability make it ideal for battery-powered and portable electronics.
