PGA300 Description
The PGA300 provides an interface for piezoresistive and strain-gauge pressure-sense elements. The device is a full system-on-chip (SoC) solution that incorporates a programmable analog front-end (AFE), ADC, and digital signal processing that enable direct connection to the sense element. Further, the PGA300 includes integrated voltage regulators and an oscillator, thus minimizing the number of external ponents.
