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: MAX187—internal reference, offset nulled; MAX189–external +4.096V reference, offset nulled. Excludes reference errors.
Note 4: Guaranteed by design. Not subject to production testing.
Note 5: External load should not change during conversion for specified ADC accuracy.
Note 6: DC test, measured at 4.75V and 5.25V only.
Note 7: To guarantee acquisition time, t
