Working Principles

The MAX9916EKA+CGJ is an operational amplifier designed to amplify small electrical signals with high accuracy and low noise. It operates by taking the difference between the voltages at its non-inverting and inverting inputs and amplifying this difference by a fixed gain. The amplified output is then available at the output pin, which can swing from the positive power supply voltage to the negative power supply voltage (rail-to-rail).
