MAX5886
3.3V, 12-Bit, 500Msps High Dynamic
Performance DAC with Differential LVDS Inputs
_______________________________________________________________________________________ 5
Note 1: Nominal full-scale current I OUT = 32 ✕ I REF .
Note 2: This parameter does not include update-rate depending effects of sin(x)/x filtering inherent in the MAX5886.
Note 3: Parameter measured single ended into a 50
Ω 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.
