TLV320DAC3101 Power consumption per rail

Timothy Starr

Hello-

We are using the 'DAC3101 in a portable product and are designing the power subsystem. The DAC3101 has 6 different power rails: AVDD, DVDD, IOVDD, HPVDD, SPRVDD, and SPLVDD. What is the maximum current draw for each of these? We have read section 5.3 of the data sheet, but it does not seem to cover the entire part, only the DAC, and it is unstated which rails are being loaded. Thanks very much,

Hi, Tim,

Sorry we missed this yesterday. I have escalated this to the responsible apps engineer.

Hi, Tim,

Sorry, I accidentally asked the wrong guy to look into this. I have corrected this, and the right guy (Dominik) will respond to your request on Monday (I doubt he will have the final answer as this data is not readily available, and will require some archaeological digging).

The DAC3101 is a subset of the AIC3111. We have a power supply application note for the AIC3111, which is also applicable to the DAC3101 for use-cases that are supported by the DAC3101:
