The AFEx32A3W 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). On channel 0, use the REF-GAIN-0 bit in the DAC-0-GAIN-CONFIG register to achieve gains of 1.5 ×, 2 ×, 3 ×, or 4 × for the DAC output voltage (VOUT). Similarly on channel 1, use the REF-GAIN-1 bit in the DAC-1-GAIN-CMP-CONFIG register. Equation 1 shows the DAC transfer function using the internal reference, in Volts.
