Automotive Catalog Programmable Sensor Signal Conditioner w/ Microcontroller

Automotive Catalog Programmable Sensor Signal Conditioner w/ Microcontroller - PGA400-Q1
 

Description

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