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, ...)?
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.
