ELECTRICAL CHARACTERISTICS (continued)

(AVDD = DVDD = 2.7V to 3.6V (MAX1041/MAX1043/MAX1047/MAX1049), external reference VREF = 2.5V (MAX1041/MAX1043/

MAX1047/MAX1049), AVDD = DVDD = 4.75V to 5.25V (MAX1040/MAX1042/MAX1046/MAX1048), external reference VREF = 4.096V

(MAX1040/MAX1042/MAX1046/MAX1048), fSCLK = 4.8MHz (50% duty cycle), TA = -40°C to +85°C, unless otherwise noted. Typical

values are at AVDD = DVDD = 3V (MAX1041/MAX1043/MAX1047/MAX1049), AVDD = DVDD = 5V (MAX1040/MAX1042/

MAX1046/MAX1048), TA = +25°C. Outputs are unloaded, unless otherwise noted.)
