PRODUCTION DATA
To enter current-output mode for each DAC channel, disable the respective IOUT-PDN-X bits in the COMMON-CONFIG register, and set the respective VOUT-PDN-X bits in the same register to Hi-Z power-down mode. Select the desired current-output range by writing to the IOUT-RANGE-X bit in the DAC-X-IOUT-MISC-CONFIG register. To minimize leakage in current-output mode, disconnect the FBx pin. For the best power-on glitch performance, program the NVM with IOUT mode using the smallest output range before powering on the output channel, and then immediately program the DAC code and desired output range. The transfer function of the output current is shown in the following equation:
where:
