TPA2012D2: Input Impedance under Shutdown Mode

Part Number: TPA2012D2

Dear Support team,

Please tell me about the input impedance of TPA2012D2 under shutdown mode.

When the SDL-pin and/or SDR-pin are driven low, the system enters shutdown mode.
Does the input impedance determined by the gain setting change at this time or does not it change?


Best Regards,
Hiroaki Masumoto

  • Hi Masumoto-san,

    Input impedance should remain the same during SDx pull-down.
