Hi , 

We are trying to work with the attached 1Mhz Transducer connected to the  BOOSTXL-TUSS4470 EVB.

What are the required BPF configurations in the GUI  ? 

Thanks :)

    Hello Dror,

    Thanks for posting to the sensors forum! The TUSS4470 does not have a bandpass filter configuration with the center frequency at 1MHz, you can configure the device in a highpass filter mode to ensure that you don't attenuate the 1MHz signal.

    You can achieve this by programming the BPF_CONFIG_1 = 0x5F, setting BPF_BYPASS to HPF frequency and by configuring BPF_HPF_FREQ to a value anywhere from 0x10 - 0x1F which sets the corner frequency of the HPF to 400kHz.

    I hope this helps!

    Best,

    Isaac
