Ulta low power DACs
« on: October 13, 2017, 01:24:23 am »
As usual I have been put to task finding an ultra low power precision DAC. Product power budget is set at 500mW total. There are a zillion DACS out there so just asking if someone here has dealt with finding such a part. It has to be 16 bits, SPI input, and I think separate power supply for the analog output would be best but not necessary. Thank you in advance!

You didn't mention what sample rate (SPI suggests an upper limit of a few Msps at most) but 500mW is not typically "low power". Did you mean 500uW?

The 500mW is the total system power budget including 2 ADC's, FPGA, uP, and 5 DAC channels. So single digit mW's or lower is needed. I may have to utilize shutdown mode to realize that kind of average power.

An FPGA too ? in 500 mW ? Which one, can I ask ?
