TLP-USR01X is an ultra-small size ultrasonic sensing module that integrates a wide-band MEMS silicon microphone, power management, frequency-selective amplifier circuit and voltage comparator, and provides both analog output and digital logic output.
It is divided into two models: TLP-USR01L and TLP-USR01H .
The amplifier configuration of TLP-USR01L is a band-pass filter with a center frequency of 40kHz .
The amplifier configuration of TLP-USR01H is a high-pass filter with a bandwidth inflection point of 50kHz .
Developers can read the information provided in the second half of this manual and adjust the desired frequency range, filtering pattern, and amplification gain by changing a few resistors and capacitors.
