TLV320AIC3100: TLV320AIC3100

Part Number: TLV320AIC3100

Hi Team,

I have a mistake, swap between pin 20 to 21

In case that I don’t use speaker I intend to cut leg 20 from HPVDD33 and pin 21 will stay with GND

Is it acceptable? later I will fix the layout

Thanks,

Shlomi

    Hi, Shlomi,

    Cutting the leg of pin 20 [SPKVSS] and leaving pin 21 [SPKVDD] connected to GND is not a recommended workaround as this connection was never tested so we cannot guarantee the part will behave as indicated in the datasheet. Given that said, in theory if the speaker amplifier is not used, the rest of the functional blocks of the device might be able to work.

    Best Regards,
