PRODUCTION DATA
The DACx300x contain 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 bit in the DAC-X-VOUT-CMP-CONFIG register to achieve gains of 1.5x, 2x, 3x, or 4x for the DAC output voltage (VOUT). Equation 3 shows DAC transfer function using the internal reference.
