Working Principles

The MAX189BCPA is a signal conditioning amplifier that amplifies analog signals with high precision and low noise. It operates by taking the input signal and amplifying it according to the gain set by external resistors connected to the IN+ and IN- pins. The amplified signal is then available at the OUT pin, which provides a rail-to-rail output swing.
