Have a question about qmc_gain setting, qmc_gainA/B(10:0) and qmc_gainC/D(10:0). The range is from 0 to 1.9990. what the register value would be when 1.5 and 1.999. Thanks.

Ying,

The maximum of 1.999 is represented as decimal 2048 for register, and unity of 1.0 is represented as decimal 1024. you can use the DAC3484 GUI to figure out the necessary hex value for the QMC gain range.

That confirms what I thought (we don't have Eval board). Thanks.
