Note 1: MAX1102/MAX1104 tested with V_DD = +3V. MAX1103 tested with V_DD = +5V.
Note 2: Relative accuracy is the deviation of the analog value at any code from its theoretical value after the gain error and offset
error have been nulled.
Note 3: Gain error calculation is referenced to the ideal FS output. Gain error for the MAX1102/MAX1103 also includes reference ini-
tial accuracy error.
Note 4: Wake-up time is the time it takes for the DAC output to settle to within ±1/2 LSB of the FS value after a power-up command.
Note 5: Output settling time is measured by taking the DAC from code 00hex to FFhex.
