Temperature Sensing, and GPIO Ports
ELECTRICAL CHARACTERISTICS (continued)
(VAVDD = VDVDD = 2.7V to 3.6V (MAX1057), external reference VREF = 2.5V (MAX1057), VAVDD = VDVDD = 4.75V to 5.25V
(MAX1020/MAX1022/MAX1058), external reference VREF = 4.096V (MAX1020/MAX1022/MAX1058), fCLK = 3.6MHz (50% duty cycle),
TA = -40°C to +85°C, unless otherwise noted. Typical values are at VAVDD = VDVDD = 3V (MAX1057), VAVDD = VDVDD = 5V
(MAX1020/MAX1022/MAX1058), TA = +25°C. Outputs are unloaded, unless otherwise noted.)
