Other Parts Discussed in Thread: PGA460
At present, there are some blind spots in the use of pga460, which is caused by residual vibration of ultrasonic probe . May I ask how to add residual vibration elimination circuit in pga460?

Hi Alex,
See the PGA460 Ultrasonic Module Hardware and Software Optimization section 3.4 Passive Tuning. This section describes how to use a tuning capacitor and/or damping resistor in parallel to the transducer to critically damp the transducer's residual decay energy to improve short ranging performance.
