PGA300ARHHR, Sensor Interface PGA300 Signal Conditioner and Transmitter for Pressure Sensors 36-VQFN -40 to 150

Semiconductors\Interface ICs\Sensor InterfacePGA300 Signal Conditioner & TransmitterTexas Instruments PGA300 Signal Conditioner and Transmitter provides an interface for piezoresistive and strain-gauge pressure-sense elements. The device is a complete system-on-chip (SoC) solution incorporating programmable analog front end (AFE), ADC, and digital signal processing. These combined elements enable direct connection to the sensing element. The PGA300 also includes integrated voltage regulators and an oscillator, thus minimizing the number of external components. The Texas Instruments PGA300 achieves high accuracy by employing third-order temperature and nonlinearity compensation. External communication is performed using a one-wire serial interface (OWI) through the power-supply pin to simplify the system calibration process. An Integrated DAC supports absolute voltage, ratiometric voltage, and 4mA to 20mA current loop outputs.
