Working Principles

The LT6003CDC is a precision amplifier that operates with low power consumption. It features rail-to-rail input and output, allowing the amplifier to accept and deliver signals close to the supply rails. This enables maximum signal swing and minimizes distortion.

The amplifier utilizes a differential input stage followed by a gain stage and an output buffer. The input stage provides high common-mode rejection ratio (CMRR) and low input offset voltage, ensuring accurate amplification of small differential signals. The gain stage amplifies the signal with high precision and low distortion. Finally, the output buffer provides a low impedance drive to the load.
