Working Principles

The PGA305ARHHT is an analog front-end IC designed to condition and amplify sensor signals. It operates by receiving the sensor signal at the input pins (IN+ and IN-) and amplifying it with a programmable gain. The amplified signal is then available at the output pin (OUT) for further processing. The built-in reference voltage generator ensures accurate calibration of the amplifier. The IC operates within a specified supply voltage range and temperature range.
