Working Principles

The AD8138ARMZ is a high-speed differential amplifier designed to amplify the difference between two input signals while rejecting any common-mode noise. It utilizes a combination of internal circuitry, including operational amplifiers and feedback networks, to achieve high gain and accurate signal reproduction.

The amplifier operates by amplifying the voltage difference between the IN+ and IN- inputs, while suppressing any voltage that appears at both inputs simultaneously. This allows it to effectively amplify differential signals while rejecting common-mode interference.
