Note 1:
All WLP devices are 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by
design and characterization.
Note 2:
For DC accuracy, the MAX11646 is tested at VDD = 5V and the MAX11647 is tested at VDD = 3V, with an external refer-
ence for both ADCs. All devices are configured for unipolar, single-ended inputs.
Note 3:
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 4:
Offset nulled.
Note 5:
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 6:
A filter on the SDA and SCL inputs suppresses noise spikes and delays the sampling instant.
Note 7:
The absolute input voltage range for the analog inputs (AIN0/AIN1) is from GND to VDD.
Note 8:
When the internal reference is configured to be available at REF (SEL[2:1] = 11), decouple REF to GND with a 0.1F capaci-
tor and a 2k
Ω series resistor (see the Typical Operating Circuit).
Note 9:
ADC performance is limited by the converter’s noise floor, typically 300VP-P.
Note 10: Measured as follows for the MAX11647:
and for the MAX11646, where N is the number of bits:
Note 11: A master device must provide a data hold time for SDA (referred to VIL of SCL) to bridge the undefined region of SCL’s
falling edge (see Figure 1).
Note 12: The minimum value is specified at TA = +25°C.
Note 13: CB = total capacitance of one bus line in pF.
Note 14: fSCL must meet the minimum clock low time plus the rise/fall times.
