Idea's --- erm , Power Op-Amp-- There used to be some in this package. Power regulator of some sort. Motor driver. Stepper motor driver even ? Perhaps a dedicated TV frame output stage. T.V. -- S.M.P.S.U. I Dunno

It "looks" old. Has that 1980's ish look.
You've no idea what it was in ?

Low power amplifier

Mooly · 16th July 2008, 04:19 PM

Well done. LA prefix of course.

Mayank · 16th July 2008, 04:26 PM

Bravo

I too tried searches with various prefixes inluding LA but didn't drop the extra "A".

i don't read japanese, but i can read graphs ok.... 0.75W or so before clipping into 8 ohms. at 1% distortion, it looks like an output amp for a table radio or a tv set. actually the data sheet sets really loose specs of 0.5W at 10%THD

redrabbit · 20th July 2008, 08:11 PM

Maybe I'll make a headphone amp with it, as a benchmark for "high distortion"....so I know what to listen for...
