The PGA400-Q1 is an interface device for piezoresistive, strain gauge, andcapacitive-sense elements. The device incorporates the analog front end (AFE) that directlyconnects to the sense element and has voltage regulators and an oscillator. The device alsoincludes a sigma-delta analog-to-digital converter (ADC), 8051 WARP core microprocessor, and OTPmemory. Sensor compensation algorithms can be implemented in software. The PGA400-Q1 also includestwo digital-to-analog converter (DAC) outputs.
