Working Principles

The THS4275DGKRG4 is a voltage-feedback operational amplifier that amplifies input signals with high speed and low distortion. It operates by receiving an input voltage at the non-inverting terminal (IN+) and amplifying it based on the feedback provided through the external components connected to the IN- terminal. The amplified output signal is then available at the OUT+ terminal.
