How to get a precise amount of voltage
April 6, 2009
I am working on my ISD4002 chip and i am now going through the recording part. This is what the manual says:
"[...] a 32 mVp-p (peak-to-peak) maximum signal should be capacitatively connected to this pin for optimal sound quality"
My question is: how can i be sure the right amount of voltage is gonna enter that ANA IN+ pin? I am also not sure how to measure the source voltage (coming from the "line out" hole from my computer).
