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