OP400GP

OP400GP Description

The OP400GP from Analog Devices Inc. is a quad general-purpose operational amplifier designed for precision analog applications. Housed in a 14-pin DIP (Through Hole) package, this IC integrates four independent op-amps with low input bias current (750 pA) and minimal input offset voltage (80 µV), ensuring high accuracy in signal conditioning. Operating within a 6V to 36V supply range, it delivers stable performance across industrial temperature ranges (0°C to 70°C). With a gain bandwidth product of 500 kHz and a slew rate of 0.15V/µs, the OP400GP balances speed and precision, making it suitable for DC and low-frequency AC applications.

OP400GP Features

• Quad-channel design: Integrates four op-amps in a single package, reducing board space and cost.
• Low power consumption: 600µA supply current per channel enhances energy efficiency.
• High precision: 80 µV offset voltage and 750 pA input bias current minimize errors in sensitive circuits.
• Wide supply range (6V–36V): Supports diverse power configurations.
• Differential output: Ideal for applications requiring noise rejection.
