Title: Data Sheet help - 18V Supply Voltage
Post by: Chi_Boy on July 28, 2013, 08:21:28 PM
Hey guys,

I'm pretty sure I'm over thinking this, but I read something on the forum and it's biasing my judgment.

I have a JRC4580/NJM4580 and I want to supply it with 18V instead of the usual 9V.

The data sheet says +18V/-18V for the supply, but that's for a dual rail supply, so straight 18V like we use is fine, right?

I've never run anything at 18V, so I just want to be sure.

This is the datasheet: http://www.mouser.com/ds/2/294/NJM4580_E-218114.pdf (http://www.mouser.com/ds/2/294/NJM4580_E-218114.pdf)

Thanks,
George

Make sure the capacitors are sufficiently rated too.

Yes, 18v single ended is fine. As TPR states, make sure your caps are rated at least 25v.
