I am designing a parking assitance system based on the PGA460. Reading the "slaa732.pdf" it sugests adding a tuning capacitor and a tunable transformer. But "TIDA-01597" deploys a standard fixed central tab transformer. The system I am designing is a 24V system for truck/traillers. Distances must range from 25cm to 2,5 m. How critical are those components fot matching the impedances? Depends on the ultrassnic sensores selected? I would like to avoid this tunning process at the end of the production.
Thank you
