TPA0211: Outpur impedance at shutdown

Part Number: TPA0211

Dear Specialists,

My customer is considering TPA0211 and has a question.

I would be grateful if you could advise.

---

According to the datasheet P.17 9.4.1 Shutdown Mode, while in shutdown mode, the device output stage is turned off.

Does this mean the output is high impedance?

I appreciate your great help in advance.

Best regards,

Hi Shinichi,

Considering that when SE mode is enabled Vo- goes into Hi-Z, I think it is OK to assume that when device enters shutdown mode both outputs will go Hi-Z.
