Note 1:
Tested at V
DD
= +5V.
Note 2:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the full-scale range has
been calibrated.
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
ACQ
is the maximum time the device takes to acquire the signal, and is also the minimum
time needed for the signal to be acquired.
