Hi,

Which of the following commands should be written when using DAC-A/B with Gain=2 using internal reference?

1) [C2:C0]=111, [DB]=1 (8.4.4 Internal Reference Enable Register)

2) [C2:C0]=000, [A2:A0]=010, [DB1:DB0]=00 (8.4.2 Gain Function)

Best Regards,

Hi Nishie,

You only need to write the first command to enable the reference. If you want gain option other than 2, you would need to enable the internal reference which resets the gain for all DACs to 2, and then use the second command to change the gain.
