Hi team,
I hope you could help us with this. Our customer is using the TLV320DAC3120, however, the Class-D driver is not powering up. In this IC, there is no speaker output voltage(spkp1,spkM2,spkp2,spkM2), but I2C AND I2S Communication is running fine. There is no voltage when giving the command register 37 and the 4th bit is not changing and it shows class-D drive powder down. The customer has checked with a multimeter, and It shows 0V and spkp1 with respect to ground is 2.5V.
Regards,
Carlo
