TLV320AIC3107: Block diagram of Power supply rails

Part Number: TLV320AIC3107

Hi Team,

There are lots of power supply rails in TLV320AIC3107 such as AVDD_ADC, AVDD_DAC, DRVDD, IOVDD, DVDD, and SPVDD. But there is no internal block diagram of power supply rails in datasheet. It will help me and my customer understand what block is supplied by each power supply rail. Please share it with me, or explain on it if TI doesn't have the related document.

Regards,

    Hello Jeffrey,

    The full internal architecture details are not shared externally, but we'll provide the high level guidance.

    AVDD_ADC:  Powers the analog portions of the ADC and ADC front end PGA/amplifier and MUX circuitry

    AVDD_DAC:  Powers the analog portions of the DAC and the DAC output stage circuitry

    DRVDD:  Powers the headphone driver circuitry (HPLOUT, HPROUT, HPCOM)

    SPVDD:  Powers the Class-D amplifier output stage (SPOP, SPOM)

    IOVDD:  Powers the internal I/O level buffers that the digital communication will operate at - set to same voltage you're communicating with the device at

    DVDD:  Powers the remaining digital portions of the ADC/DAC, digital processing, and other digital parts of the device

    Hi  Collin,

    Thanks for your kind response. It will help my customer understand the internal architecture of all power rails.

    Regards,
