TPA2012D2: Input Impedance under Shutdown Mode

Hiroaki Masumoto

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?

Hi Masumoto-san,

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