Wolfson WM8741 power consumption

[janos_904]

Hi, I am going to tweak my Wolfson WM8741 chip based DAC (opus). I would like to know the power consumption of ADDR and/or ADDL legs (chip legs No9 and 20). I could not find any information, just the consumption of AVDD (50mA). Thanks, János

Nobody knows?

Looking at the datasheet there isn't any pins labeled ADDR and/or ADDL

Pin 9 is AVDDR Right Analogue input and Pin 20 is AVDDL Left Analogue input

Recommended operating conditions are, at 5v, 55ma.

OK, I misstyped the labels, the correct name is AVDDL and AVDDR. To make the goal clear: all this two pins and AVDD (pin15) need 5 V supply. What do you think about 55 mA, is the sum of current consumption of three pins?

It's the sum of consumption of the chip.
