[sdiy] JRC4558DX Question

[mike ruberto]

Well I am watching them operate in a circuit with +-22V. The circuit
was designed with this supply voltage and still works after 29 years.
So my thoughts here is the this must be a higher voltage version of
the JRC4558.
Just wish I could find a datasheet to verify it.
