Note 4:
This parameter does not include update-rate depending effects of sin(x)/x filtering inherent in the MAX5878.
Note 5:
Parameter measured single-ended into a 50
termination resistor.
Note 6:
Not production tested. Guaranteed by design.
Note 7:
No termination resistance between XORP and XORN.
Note 8:
A differential clock input slew rate of >100V/μs is required to achieve the specified dynamic performance.
Note 9:
Parameter defined as the change in midscale output caused by a ±5% variation in the nominal supply voltage.
