I make device based on the CN0129.
Outs EXCA and EXCB AD7745 make in inverse mode signal with not full amplitude.
in the oscillogram i show 2 outs in direct and inverse mode,
in direct mode EXCA and EXCb working right wih amplitude of supply voltage.
when switch one of outs in the inverse mode reg_EXC_setup = 0x3B or 0x2F
i see full amplitude 4,5 V in the direct outputs, and signal with amplitude 260 mV
on inverse EXCA or 100 mV in inverse EXCB.
What that can be?
Resistor 100 kOm not should be load outs.
I am solded 3 different ICs, bying from 2 seller, and see the same effect.
Thanks fo help.
