Funny, I was just looking at the data sheet last night. I have to scan it to PDF & I'll post it tomorrow if I remember to bring it to work to scan.

Hi mlloyd1,

I'm the original designer of the PA630/PA630A chips. All the documentation was done back in 1990, with old obsolete software. As a result, for many years, only hard copies existed.

Recently, I bit the bullet and scanned a lot of this information, but the files are large. If there is enough interest, perhaps I could post some of this somewhere on this board.

Unfortunately, the actually PA630/PA630A ICs have been long out of production and are essentially unavailable.

However, I am working on an updated and simplified version that is called the PA631. My initial application is in a headphone amplifier that will have NO global feedback - just buffers and the current conveyor to provide the gain.

Stay tuned for more information.

Speaking of current conveyors, I'd be curious about a BJT version of this:

Oops, I had not noticed how old this thread was. Looks like Linear hasn't been online here since 2007.
