_______________________________________________________________________________________
Note 2: Limits at TA = -40°C are guaranteed by design and not production tested.
Note 3: The MAX11639/MAX11643 tested at VDD = +3V. The MAX11638/MAX11642 tested at VDD = +5V.
Note 4: Offset nulled.
Note 5: Time for reference to power up and settle to within 1 LSB.
Note 6: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 7: See Figure 3 (Equivalent Input Circuit) and the Sampling Error vs. Source Impedance curve in the
Typical Operating
Characteristics section.
Note 8: When CNVST is configured as a digital input, do not apply a voltage between VIL and VIH.
Note 9: Supply current is specified on whether an internal or external reference is used for voltage conversions.
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +2.7V to +3.6V (MAX11639/MAX11643), VDD = +4.75V to +5.25V (MAX11638/MAX11642), fSAMPLE = 300kHz, fSCLK =
4.8MHz (external clock 50% duty cycle), VREF = 2.5V (MAX11639/MAX11643), VREF = 4.096V (MAX11638/MAX11642), TA = TMIN to
TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 2)
