(AVDD = DVDD = 2.7V to 3.6V (MAX1021/MAX1023/MAX1057), external reference VREF = 2.5V (MAX1021/MAX1023/MAX1057), AVDD =
DVDD = 4.75V to 5.25V (MAX1020/MAX1022/MAX1058), external reference VREF = 4.096V (MAX1020/MAX1022/MAX1058), fSCLK = 4.8MHz
(50% duty cycle), TA = -40°C to +85°C, unless otherwise noted. Typical values are at AVDD = DVDD = 3V (MAX1021/MAX1023/MAX1057),
AVDD = DVDD = 5V (MAX1020/MAX1022/MAX1058), TA = +25°C. Outputs are unloaded, unless otherwise noted.)
