I am trying to attenuate the stereo signal in an RCA cable. I would like it to do exactly what this product does:
http://www.amazon.com/gp/product/B0...1-99ac-45e5-8c23-e9e0811a2b2c&pf_rd_i=desktop
However, instead of using a knob, I would like to control it from a 0 - 5 volt signal. 0v translating to a gain of 0, and 5 volts translating to a gain of 1 or something similar to that.
I found this attenuator but I had a hard time understanding the data sheet. http://www.farnell.com/datasheets/1846875.pdf Is this what I am looking for?
