(Note 2)
Note 2: Specifications at T
A
≥ +25°C are guaranteed by production testing. Specifications at T
A
< +25°C are guaranteed by design
and characterization data.

.
Note 4: This parameter does not include update-rate-dependent effects of sin(x)/x filtering inherent in the MAX5874.
Note 5: Parameter measured single-ended into a 50Ω termination resistor.
Note 6: Not production tested. Guaranteed by design and characterization data.
Note 7: A differential clock input slew rate of > 100V/µs is required to achieve the specified dynamic performance.
Note 8: Parameter defined as the change in midscale output caused by a ±5% variation in the nominal supply voltage.
