Beschreibung

The TIDA-00793 reference design provides a simple, robust, and accurate sensor signal conditioning solution using the PGA301-Q1 for resistive bridge type pressure sensors. The protection strategies implemented in this design protect the pressure sensor against wiring harness faults, EMI, and automotive electrical transients. Theory, operation, and challenges involved in the design are systematically explained in the design guide.
