Working Principles

The PGA205AP is a precision programmable gain amplifier designed to accurately amplify analog signals. It utilizes an internal operational amplifier (op-amp) with a digitally controlled resistor network to achieve variable gain settings. The gain can be programmed using external resistors connected to the RG pin. The amplified signal is available at the OUT pin, while the IN+ and IN- pins serve as the differential input. The REF, SET, and NC pins are not used in this device.
