TAS5622A: IGVDD current too high

Hi Kevin

Did you measure them at the same condition with datasheet?

could you share more detail how you perform the test?

BTW, I found that the circuit is a little different with our recommend circuit, they seem missing one 10uF capacitor be connected to GVDD.

It will better to add that and test again.

Hi Jesse,

The measurement method is no load,
No signal to test IGVDD,
According to the suggestion, add a 10U capacitor test in the place close to VDD,
IGVDD_AB and IGVDD_CD have a decrease of 0.8mA,
IGVDD measurement is about 21.2mA,
What I want to confirm is that the datasheet indicates that IGVDDX is 12mA current,
But my current test is 21.2mA, is there any risk?

Hi Kevin

it should have no problem. 12mA is just a typical value.

can you inform me what kind of tester you use?

Hi Jesse

Use a multimeter for the measurement results, or is there a better measurement suggestion?
