The PGA305 device supplies an interface for piezoresistive and strain-gauge pressure-sense elements. The device is a full system-on-chip (SoC) solution that includes programmable analog front end (AFE), ADC, and digital signal processing that enable direct connection to the sense element. The PGA305 device also includes integrated voltage regulators and an oscillator to minimize the number of external components. The PGA305 device can employ third-order temperature and nonlinearity compensation to achieve high accuracy. The device can also use the integrated I2C interface or the one-wire serial interface (OWI) to achieve external communication and simplify the system calibration process. An Integrated DAC supports absolute-voltage, ratiometric-voltage, and 4-mA to 20-mA current-loop outputs.
