BOOSTXL-PGA460: Frequency Range

Olivia Ehrman
Prodigy 30 points
Part Number: BOOSTXL-PGA460
Other Parts Discussed in Thread: PGA460

Tool/software:

Hello,

If I connect the BOOSTXL to a piezo transducer with a slightly higher resonant frequency than in the range given in the BOOSTXL data sheet (e.g., 600-700 kHz piezo resonant frequency when the given high frequency range for the board is 180-480 kHz), would that just give back noisy data, or would that physically damage the board?

Thank you,

Olivia

    Hello Olivia,

    Thanks for posting to the sensors forum! You wouldn't damage the board by using a transducer with a higher frequency but the data you receive back would most likely look like noise since the transducer is not being excited to the proper frequency or you wouldn't see any return data since the frequency is incorrect.

    If you need a higher frequency try looking at our BOOSTXL-TUSS4470EVM, since it can handle frequencies all the way up to 1MHz. It is not as integrated as the PGA460 but it can handle the frequencies you used in your example.

    Best,

    Isaac
