TAS6424-Q1: CURRENT SPECS

Part Number: TAS6424-Q1

Dear

What is the current needed for VBAT? We want to use TAS6424QDKQRQ1 at 24V, but VBAT can't handle that so we need a seperate supply for that. What current should be able to be supplied?

Greetings

Thomas,

VBAT current is specified at page 7 electrical table. it is 100mA at play mode.

That says idle current 100mA?

IVBAT_IDLE VBAT idle current All channels playing, no audio input 90 100 mA

When there is no audio input. So that is not useful ...

Thomas,

VBAT current is for internal analog circuit use. So as long as device is in play mode(PWM is switching and analog circuit is working), the VBAT current will be there, which will not increase when play audio power. play audio power only impact PVDD.
