Part Number: DRV5055

Hi Team,

May I know the output impedance of DRV5055? 

Thanks and Best Regards!

Hao

  • Dear Hao,

    Here is the Output Impedance for the DRV5055A4 over frequency. Unfortunately, this is the only variant I have this graph for, but the other variants are similar. Let me know if you have any questions.

    Hi Carolus,

    Thanks for sharing this graph. Does the X axis mean the input frequency of the detected magnetic? I remember the bandwidth of DRV5055 is 20kHz, the X axis in the graph is larger than 20kHz.

    Thanks and Best Regards!

    Hao,

    The frequency in this graph is referring to the frequency of the load you are attempting to drive here, not the input frequency of the device itself. This is often important if the output is being used as a direct feedback line in a system.
