ELECTRICAL CHARACTERISTICS (continued)
(V
Typical values are at T
Note 1: 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: The operational input voltage range for each individual input of a differentially configured pair is from GND to V
Note 6: See Figure 3 (Input Equivalent Circuit) and the Sampling Error vs. Source Impedance curve in the Typical Operating
Note 7: Fast automated test, excludes self-heating effects.
Note 8: When CNVST is configured as a digital input, do not apply a voltage between V
Note 9: Supply current is specified depending on whether an internal or external reference is used for voltage conversions.
