Hello everybody,
I have a question about PGA4311. What is the output impedance of this chip? I want to connect the output with the input to realize two-stage volume control (pre volume and master volume). I read in datasheet then: "For optimal performance, it is best to drive the PGA4311 with a low source impedance. A source impedance of 600Ω or less is recommended."
Thanks for any help.
