Diff between 4558D and 4558DD?
Someone recently gave me a JRC4558DD chip. How does this chip differ, in terms of technical specs, from the JRC4558D? (What does that extra D in the suffix mean?) Are the D and DD versions interchangeable?

The extra "D" means the part was screened for lower noise performance. They can screen the parts for any parameter you want, if you're buying enough, and they identify them by adding a second letter to the part number.
