PRODUCTION DATA
The DAC539E4W provides an external reference input (MODE pin). Select the external reference option by configuring the VOUT-GAIN-x field in the DAC-x-VOUT-CMP-CONFIG register appropriately. In case the MODE pin functionality is not used, write 1 to the DIS-MODE-IN bit in the DEVICE-MODE-CONFIG register to minimize quiescent current. The external reference can be between 1.8 V and VDD. Equation 3 shows the transfer function of the threshold DAC when the external reference is used.
