TIDA-00149, Automotive Capacitive Pressure Sensor Interface

TIDA-00149, Automotive Capacitive Pressure Sensor Interface. This TIDA-00149 reference design utilizes a fully integrated SOC (System on a Chip) as an interface device for piezoresistive, strain gauge and capacitive sense elements. The device incorporates the analog front end that directly connects to the sense element and has voltage regulators and oscillator. The device also includes sigma-delta analog-to-digital converter, 2 DAC outputs, 8051 WARP core Microprocessor and OTP memory. Sensor compensation algorithms can be implemented in software which enables a fully configurable system that can be modified to support multiple sensor elements
