Table 7 and Table 8 show the ideal input code to output voltage
relationship for the AD5764 for both offset binary and twos
complement data coding, respectively.
where:
D is the decimal equivalent of the code loaded to the DAC.
VREFIN is the reference voltage applied at the REFAB/REFCD pins.

CLR is a negative edge triggered clear that allows the outputs to
be cleared to either 0 V (twos complement coding) or negative
full scale (offset binary coding). It is necessary to maintain CLR
low for a minimum amount of time (see
) for the operation
to complete. When the
CLR signal is returned high, the output
remains at the cleared value until a new value is programmed. If
at power-on, CLR is at 0 V, then all DAC outputs are updated
with the clear value. A clear can also be initiated through software
by writing Command 0x04XXXX to the AD5764.
