Working Principle of MAX400CPA+

The MAX400CPA+ uses a Bipolar Junction Transistor (BJT) to achieve low offset, low temperature coefficient, and high common-mode rejection ratio. It consists of two NPN BJTs that are configured in a differential Pair configuration with a negative Feedback Loop. The differential pair configuration provides the ability to amplify both differential and single-ended input signals. The feedback loop provides precise gain control, offset control and temperature compensation. The device also has a high input resistance and high output current capability, making it ideal for use in high gain and high bandwidth applications.

The amplifier also features a low bias current, making it ideal for power supply rejecting, low voltage, noise sensitive applications. Its low temperature coefficient and low offset, combined with its high common-mode rejection (CMRR) make it ideal for automotive, industrial and medical applications.
