PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The DAC539E4W contains an internal reference that is disabled by default. To enable the internal reference, write 1 to bit EN-INT-REF in the COMMON-CONFIG register. The internal reference generates a fixed 1.21-V voltage (typical). Use the VOUT-GAIN-x field in the DAC-x-VOUT-CMP-CONFIG register to achieve gains of 1.5 ×, 2 ×, 3 ×, or 4 × for the DAC output voltage (VTHLD). Equation 2 shows DAC transfer function using the internal reference.
