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: Internal reference, offset, and reference errors nulled.
Note 4: Conversion time is defined as the number of clock cycles multiplied by the clock period; clock has 50% duty cycle.
Note 5: External load should not change during conversion for specified accuracy. Guaranteed specification limit of 2mV/mA due to
Note 6: Electrical characteristics are guaranteed from V
Note 7: MAX1084 tested with 20pF on DOUT and f
