Working Principles

The PGA309AIPWRG4 is a signal conditioning amplifier designed to amplify and condition sensor signals. It utilizes a programmable gain amplifier (PGA) architecture to provide precise amplification with adjustable gain settings. The offset calibration feature allows for accurate measurement of small signals by eliminating DC errors.

The device operates by receiving the sensor signal at the IN+ and IN- pins, which are differential inputs. The amplified and conditioned output signal is available at the OUT pin. The VREF pin provides a reference voltage for the PGA.
