Analog Waveform Output
4
TUSS44x0 supports a demodulate log amp output that must be captured by an external ADC for post-processing to extract the time-of-flight information.
TUSS4470 400 kHz Ranging at 20-V Driver Example

Hybrid Output
5
TDC10xx generates an output pulse on the START pin, which is used as the time reference to begin a TOF measurement. The receiver detects the ultrasound wave that traveled through the medium and generates STOP signals.
