Other Parts Discussed in Thread: VCA5807
Hi all,
I would like to use the VCA2617 for a new design. I'll use it as a postamplifier to the VCA5807. In the data sheet there are two PINs (PIN 3 and PIN 6) labelled VDDR and GNDR related to an unspecified reference supply. What is it? There's nothing about it in the data sheet. What must I do with it? Looking at the evaluation module I saw that it must be connected to power supply (5V) and bypassed with 2.2uF plus 100nF.....why?What is it's function? Thanks for your replay.
Regards
Andrea
