TLV320AIC3204: DVDD

Part Number: TLV320AIC3204

Hi team,

When the internal LDO is used, can we use the DVDD power supply as also a reference voltage for other devices within 0.2mA(max)? We would like to use DVDD for not only an internal power supply but also a reference voltage for other devices.

Regards,

Ishida

    Hi, Jun,

    Using the on-chip generated DVDD to power other devices is not recommended, the internal LDO is optimized to power-up the internal circuitry of the codec only, using it to power external components may lead to device malfunction, unexpected behavior or performance issues.
