TIMING CHARACTERISTICS (Figures 5 and 6) (continued)
(AVDD = DVDD = 3.3V ±5%, TA = TMIN to TMAX, unless otherwise noted.)
Note 1: Tested at AVDD = DVDD = 3.3V, bipolar input mode.
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the gain error and offset
error have been nullified.
Note 3: Offset nullified.
Note 4: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle. Includes
the acquisition time.
Note 5: Acquisition time is 5 clock cycles in short acquisition mode and 13 clock cycles in long acquisition mode.
Note 6: Performance is limited by the converter’s noise floor, typically 300VP-P.
Note 7: When an external reference has a different voltage than the specified typical value, the full scale of the ADC scales propor-
tionally.
Note 8: Defined as the change in positive full scale caused by a ±5% variation in the nominal supply voltage.
Typical Operating Characteristics
(MAX1144/MAX1145, AVDD = DVDD = 3.3V, fSCLK = 3.6MHz, external clock (50% duty cycle), 24 clocks/conversion (150ksps),
bipolar input, REF = 2.048V, 4.7F on REF, 1F on CREF, TA = +25°C, unless otherwise noted.)
