Note 1: AV CC should be at least 0.25V higher than the maximum output voltage required from the DAC. Full-scale output is 5V for
the MAX5732.
Note 2: Linearity guaranteed from code 2047 to full scale and from (V SS + 0.3V) to (AV CC - 0.3V).
Note 3: DNL guaranteed over all codes for (V SS + 0.3V) to (AV CC - 0.3V).
Note 4: Zero-scale error is measured at code 0. Full-scale error is measured at code FFFFhex.
Note 5: DC crosstalk is the change in the output level of one DAC at midscale in response to the full-scale output change of all
other DACs.
Note 6: Digital feedthrough is a measure of the impulse injected into the analog outputs from the digital control inputs when the
device is not being written to. It is measured with a worst-case change on the digital inputs.
Note 7: Digital crosstalk is the glitch impulse transferred to the output of one DAC at midscale while a full-scale code change is written
into another DAC.
Note 8: DAC-to-DAC crosstalk is the glitch impulse that appears at the output of one converter due to both the digital change and
subsequent analog output change at another converter.
