TIMING CHARACTERISTICS (Figure 1) (continued)
(VDD = 2.7V to 3.6V (MAX1237/MAX1239), VDD = 4.5V to 5.5V (MAX1236/MAX1238), VREF = 2.048V (MAX1237/MAX1239), VREF =
4.096V (MAX1236/MAX1238), fSCL = 1.7MHz, TA = TMIN to TMAX, unless otherwise noted. Typical values are at
TA = +25°C, see Tables 1–5 for programming notation.)
Note 1: For DC accuracy, the MAX1236/MAX1238 are tested at VDD = 5V and the MAX1237/MAX1239 are tested at VDD = 3V. All
devices are configured 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: Conversion time is defined as the number of clock cycles needed for conversion multiplied by the clock period. Conversion
time does not include acquisition time. SCL is the conversion clock in the external clock mode.
Note 5: A filter on the SDA and SCL inputs suppresses noise spikes and delays the sampling instant.
Note 6: The absolute input-voltage range for the analog inputs (AIN0–AIN11) is from GND to VDD.
Note 7: When the internal reference is configured to be available at AIN_/REF (SEL[2:1] = 11) decouple AIN_/REF to GND with a
0.1F capacitor and a 2k
Ω series resistor (see the Typical Operating Circuit).
Note 8: ADC performance is limited by the converter’s noise floor, typically 300VP-P.
Note 9: Measured as for the MAX1237/MAX1239
