LM4898: Output State in Shutdown Mode

Chris Suchoski
Prodigy 200 points
Part Number: LM4898

Hello,

When the LM4898 is put into shutdown mode, can I assume that the output stage is turned off and that the output enters a high-impedance state? In particular, I would like to ensure that there is no signal pass-through from input to output when shutdown is enabled.

Thank you!

Chris

    Hi, Chris,

    Your assumption is correct, when the device enters in shutdown mode, the output is placed in high-impedance mode and there's no output signal at the speaker outputs Vo1 and Vo2.

    Please let me know if you have additional questions or comments.

    Best regards,
