MAX18_ _C/E
Note 1: Tested at VDD = 5.0V; VSS = 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 VSUPPLY +5% and VSUPPLY -5% only.
Note 9: The common-mode range for the analog inputs is from VSS to VDD.
