Note 1: Tested at V_DD = V_DD,MIN.
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: 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
production test limitation.
Note 6: Electrical characteristics are guaranteed from V_DD,MIN to V_DD,MAX. For operations beyond this range, see Typical Operating
Characteristics.
Note 7: MAX1084 tested with 20pF on DOUT and f_SCLK = 6.4MHz, 0 to 5V. MAX1085 tested with same loads, f_SCLK = 4.8MHz, 0 to
3V. DOUT = full scale.
