Hi,
I would like to ask you a basic question about the circuit of Fig76, datasheet 29page.
There are 2 input registers in the circuit, R2/R3.
I think that the input registance of VCA824 is set by the registers.
Will you tell me how to select the value of the registers?
If we would like the input registance be max, we should remove the registers (R2/R3), I suppose...
I would like to know the role of R2/R3. (Except impedance maching..)
Sorry for my basic question.
Thank you for your support.
