Is there a daisy-chainable high-precision (18+ bits) DAC

Hi,

I need to daisy-chain several AD7767 along with high-precision DACs in a way such that the DACs can be updated while reading data from the ADCs. It is a relatively large system with hundreds of ADCs/DACs. The daisy-chaining is necessary to meet my overall timing requirements.

I was thinking about using AD5791s, but then realized that they cannot be daisy chained. (The original datasheet showed a daisy-chaining mode.)

 

Is there any way to daisy-chain 5791s? Alternatively, is there a high-precision DAC with that can be daisy-chained with AD7767s (24-bit regs, similar timing, ...)?


Thanks!

    Hi Daniel,

    They may have deleted the daisy chaining for a reason. I will be contacting the design and applications engineer for the reason they have done so.

    Meanwhile, you may take a look at AD760 which is an 18-bit DAC that supports daisy chaining through the Sout pin.
