I'll try to ask to customer whether output of 2Vrms can do by only DAC or not.
Anyway, my question of analog input is about the internal circuit of IC.
As my understanding, VCCH is for the driver supply voltage. isn't it? And the operating voltage of Op amps of analog input is Vccad = 3.3V.
If my understanding is correct, the gain of op amps of analog inputs are equal or less than 1/2 for supporting 2Vrms signal level, and also it requires common bias (maybe equal to VCOMAD).
But an analog input circuit of the datasheet shows x1 op amps without bias.
So that, I would like to know the internal analog input equivalent circuit.
