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 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.
