Note 1:
Tested at DVDD = AVDD = +2.7V (MAX1233), DVDD = AVDD = +5V (MAX1234).
Note 2:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the offset and gain errors
have been removed.
Note 3:
Offset nulled.
Note 4:
Difference between TEMP1 and TEMP2; temperature in °K = (VTEMP2 - VTEMP1)
× 2680°K/V. No calibration is necessary.
Note 5:
Temperature coefficient is -2.1mV/°C. Determine absolute temperature by extrapolating from a calibrated value.
Note 6:
ADC performance is limited by the conversion noise floor, typically 300VP-P. An external reference below 2.5V can
compromise the ADC performance.
Note 7:
Guaranteed from code 5 to 255.
