TLV320AIC3254EVM-K: Measuring current consumed at AVDD and DVDD

Part Number: TLV320AIC3254EVM-K


Hello, 

The datasheet for this codec's EVM states that I can use W17 and W19 exposed wire loops to measure current. But these loops are effectively just test points. How do I go about measuring current consumption of the AIC3254 chip itself?

    Hi, Juliana,

    The loops mentioned in the user's guide are provided to give a point where user can remove/cut the wires to connect the current measurement equipment and measure the consumption of  each power supply connected to the AIC3254.

    Best Regards,
