.
Note 2:
This parameter does not include update-rate depending effects of sin(x)/x filtering inherent in the MAX5887.
Note 3:
Parameter measured single ended into a 50
termination resistor.
Note 4:
Parameter guaranteed by design.
Note 5:
A differential clock input slew rate of >100V/μs is required to achieve the specified dynamic performance.
Note 6:
Parameter defined as the change in midscale output caused by a ±5% variation in the nominal supply voltage.
