TIMING CHARACTERISTICS
(V
Note 1: Tested at V
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
Note 3: MAX149—internal reference, offset nulled; MAX148—external reference (V
Note 4: Ground “on” channel; sine wave applied to all “off” channels.
Note 5: Conversion time defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 6: The common-mode range for the analog inputs is from AGND to V
Note 7: Sample tested to 0.1% AQL.
Note 8: External load should not change during conversion for specified accuracy.
Note 9: ADC performance is limited by the converter’s noise floor, typically 300FV
Note 10: Guaranteed by design. Not subject to production testing.
Note 11: The MAX148 typically draws 400FA less than the values shown.
Note 12: Measured as |V
