PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
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.
