TAS2505: SPKVDD at 5V Power consumption

Part Number: TAS2505

Hi Sirs,

My I know the power consumption of TAS2505 at below conditions?

2W into 4Ohm Speaker output, Mono, 48 kHz, Highest Performance,
SPKVDD = 5V  -> ? mA

DVDD = AVDD = 1.8V -> ? mA

IOVDD = 3.3 V -> ? mA

    Hello, 

    The overall power consumption of the TAS2505 can be calculated by using the output power (2W as you mentioned) and dividing by the device efficiency to get the power input. You can then subtract the two numbers to get power consumption. Using 75% efficiency (which slightly below expected efficiency for this power/speaker combination), you get 0.67W of power consumption. 

    Hope this helps.

    Best Regards,
