Using a single Reference with multiple AD7768-1


I have a design that will use up to 16 (sixteen) AD7768-1 delta-sigma ADC.

Due to limited PCB area, I would like to use a single reference for all AD7768-1.

According to the AD7768-1 data sheet, the AD7768-1 has fully buffered reference inputs REF+ and REF- that provide high impedance input nodes.
From this aspect, I think it should work.

Does the use of a single Reference like LTC6655 with multiple AD7768-1 affect analog performance?

Regards, Niels
