9.4.1.1 Startup Ramp Time

During the startup ramp the CMUTE capacitor is charged by an internal current generator. With use of the recommended 33 nF CMUTE capacitor value, the startup ramp time is approximately 20 ms. Higher CMUTE capacitor value will increase the ramp time, and a lower value will decrease the ramp time. The recommended CMUTE capacitor value is selected for minimum audible artifacts during startup and shutdown ramp.
