ELECTRICAL CHARACTERISTICS (continued)
(VDD = 2.7V to 3.6V (MAX1037/MAX1039), VDD = 4.5V to 5.5V (MAX1036/MAX1038). External reference, VREF = 2.048V
(MAX1037/MAX1039), VREF = 4.096V (MAX1036/MAX1038). External clock, fSCL = 1.7MHz, TA = TMIN to TMAX, unless otherwise
noted. Typical values are at TA = +25°C.)

Note 1: The MAX1036/MAX1038 are tested at VDD = 5V and the MAX1037/MAX1039 are tested at VDD = 3V. All devices are config-
ured for unipolar, single-ended inputs.
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range and
offsets have been calibrated.
Note 3: Offset nulled.
Note 4: Ground on channel; sine wave applied to all off channels.
Note 5: Conversion time is defined as the number of clock cycles (8) multiplied by the clock period. Conversion time does not
include acquisition time. SCL is the conversion clock in the external clock mode.
Note 6: The absolute voltage range for the analog inputs (AIN0–AIN11) is from GND to VDD.
Note 7: When AIN_/REF is configured to be an internal reference (SEL[2:1] = 11), decouple AIN_/REF to GND with a 0.01F capacitor.
Note 8: The switch connecting the reference buffer to AIN_/REF has a typical on-resistance of 675Ω.
Note 9: ADC performance is limited by the converter’s noise floor, typically 1.4mVP-P.
Note 10: Electrical characteristics are guaranteed from VDD(min) to VDD(max). For operation beyond this range, see the Typical
Operating Characteristics.
Note 11: Power-supply rejection ratio is measured as:
, for the MAX1037/MAX1039 where N is the number of bits and VREF = 2.048V.
Power-supply rejection ratio is measured as:
, for the MAX1036/MAX1038 where N is the number of bits and VREF = 4.096V.
Note 12: A master device must provide a data hold time for SDA (referred to VIL of SCL) in order to bridge the undefined region of
SCL’s falling edge (Figure 1).
Note 13: CB = total capacitance of one bus line in pF. tR, tFDA, and tF measured between 0.3VDD and 0.7VDD. The minimum value is
specified at +25°C with CB = 400pF.
Note 14: fSCLH must meet the minimum clock low time plus the rise/fall times.
