I am using
the AD5732AREZ DA-converter on an SPI bus with several devices. Unfortunately
it seems that the SDO-pin don’t go to High-Z state.
As in the datasheet the high impedance input leakage current of SDO-pin is specified,
there must be a possibility to switch the pin to this state. I tried to disable
the SDO-Output in control register (SDO disable bit == 1) which prevents the IC
to send data at SDO-Pin, but it don’t seem to be in high impedance state
