TAS5825M: TAs5825M idle current

Part Number: TAS5825M

Hi support team,

We would like to know what is the idle current of the amplifier with different PVDD ( 7.4V to 20V ) and with different speaker load ( 4 to 8 ohm ). it is because the specification did not mention in detail.

Beast regards

    Hi Kelvin,

    Besides PVDD voltage, the idle current also depends on LC filter configuration, PWM frequency and modulation mode. Larger inductors and higher PWM frequency make lower idle current. And the 1SPW mode or Hybrid mode also make lower idle current than BD mode. We are generating an detailed app note for this, and will publish it soon later. For now, please find the data below:

    Bet regards,
