ELECTRICAL CHARACTERISTICS (continued)
(AVDD3.3 = DVDD3.3 = AVCLK = +3.3V, AVDD1.8 = DVDD1.8 = +1.8V, GND = 0, fCLK = 2 x fDAC, external reference VREFIO = +1.25V, out-
put load 50
double-terminated, transformer-coupled output, IOUTFS = 20mA, TA = TMIN to TMAX, unless otherwise noted. Typical values
are at TA = +25°C.) (Note 2)
Note 2: Specifications at TA
≥ +25°C are guaranteed by production testing. Specifications at TA < +25°C are guaranteed by design.
Note 3: Nominal full-scale current IOUTFS = 32 x IREF.
Note 4: This parameter does not include update-rate-dependent effects of sin(x)/x filtering inherent in the MAX5877.
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/s 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.
