Note 1:
Tested at V
DD
= 5.0V; V
SS
= 0V; unipolar input mode.
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:
MAX186 – internal reference, offset nulled; MAX188 – external reference (VREF = +4.096V), offset nulled.
Note 4:
Ground on-channel; sine wave applied to all off channels.
Note 5:
Conversion time defined as the number of clock cycles times the clock period; clock has 50% duty cycle.
Note 6:
Guaranteed by design. Not subject to production testing.
Note 7:
External load should not change during conversion for specified accuracy.
Note 8:
Measured at V
SUPPLY
+5% and V
SUPPLY
-5% only.
Note 9:
The common-mode range for the analog inputs is from V
SS
to V
DD
.
