PGA305ARHHT, Sensor Interface Signal Conditioner for Resistive Sensing With Digital and Analog Outputs 36-VQFN -40 to 150

Semiconductors\Interface ICs\Sensor InterfacePGA305 Signal ConditionerTexas Instruments PGA305 Signal Conditioner 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 pressure-sense element. The PGA305 also includes integrated voltage regulators and an oscillator to minimize the number of external components. The PGA305 can employ third-order temperature and nonlinearity compensation to achieve high accuracy. The device can also use the integrated I 2 C 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 4mA to 20mA current-loop outputs.
