Note 1: MAX11627/MAX11629/MAX11633 tested at V
Note 2: Offset nulled.
Note 3: Time for reference to power up and settle to within 1 LSB.
Note 4: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 5: See Figure 3 (Equivalent Input Circuit) and the Sampling Error vs. Source Impedance curve in the Typical Operating
Note 6: When CNVST is configured as a digital input, do not apply a voltage between V
Note 7: Supply current is specified depending on whether an internal or external reference is used for voltage conversions.
