DAC81404: Power consumption test results Request

Jagan S

Part Number: DAC81404

Hi Texas,

Greetings for the day!!

DAC81404RHBT

We are planning to use above DAC part and We need supply current of the DAC for capacitive load upto 150pF, which is required for our system power calculations.

Can you share us the power consumption results if available for internal reference mode, provided Analog VDD Supply: 26V & AVSS : 0V and Digital VDD Supply : 5V

Hi,

Max AVDD current is 8mA, DVDD current = 8mA

Hope this helps.

Hi Akhlesh K

Thanks for your faster response.

We need this IC for battery application, so 8mA max current we got from datasheet.

However in no load condition, we need typical current consumption for this IC with AVDD as 26V condition. Can you share the same

Thanks & Regards

Hi,

The numbers I quoted is for no load condition. We didn't characterize the device exactly at the AVDD you mentioned. Take it max value as 8mA

Hope this helps.
