Description for the PGA300

The PGA300 provides an interface for piezoresistive and strain-gauge pressure-senseelements. The device is a full system-on-chip (SoC) solution that incorporates a programmableanalog front-end (AFE), ADC, and digital signal processing that enable direct connection to thesense element. Further, the PGA300 includes integrated voltage regulators and an oscillator, thusminimizing the number of external components. The device achieves high accuracy by employingthird-order temperature and nonlinearity compensation. External communication is achieved by usinga one-wire serial interface (OWI) through the power-supply pin in order to simplify the systemcalibration process. An Integrated DAC supports absolute-voltage, ratiometric-voltage, and 4-mA to
20-mA current-loop outputs.
