ELECTRICAL CHARACTERISTICS (continued)
(VAVDD = VDVDD = 2.7V to 3.6V (MAX1257), external reference VREF = 2.5V (MAX1257), VAVDD = 4.75V to 5.25V, VDVDD = 2.7V to VAVDD
(MAX1220/MAX1258), external reference VREF = 4.096V (MAX1220/MAX1258), fCLK = 3.6MHz (50% duty cycle), TA = -40°C to +85°C,
unless otherwise noted. Typical values are at VAVDD = VDVDD = 3V (MAX1257), VAVDD = VDVDD = 5V (MAX1220/MAX1258), TA = +25°C.
Outputs are unloaded, unless otherwise noted.)
