Default mystery part: upd 6360c

Hi

I'm looking for any info on this part. I have managed to locate some price lists, but I'm not sure what the chip is used for.

It comes out of a graphic equaliser, a pdip package, and at first blush seems like a buffer amp. I've not seen this thing myself yet, it's quite a way away and I needed to figure if anybody had any info on the part before I got into the guts of it...

The upd6360c is used in the NAD5300.
If someone here has a schematic of the NAD, this could help you.

Thanks netlist

Any idea as to which section it is used for? Analog output buffer, brickwall filter?

It is beginning to sound more and more like an opamp, but any clue on what configuration (single, dual, quad?) and whether it is swappable with any more common chip?

Absolutely no idea; you'll have to wait till someone comes up with
more information or a schematic. Maybe you can post some more info about your EQ? Brand, type..

I think UPD is usually a NEC part and the UPD63xx series is 4-bit microcontrollers used for IR remote control functions. Can't find UPD6360C though, maybe it's custom although used in Hitachi TVs also?

The Equaliser is a 10 band per channel Technics equaliser, SH-E4, part of a compact component boom box that actually sounds pretty good. Doesn't have a CD input. awfully old.

Probably custom, but maybe you're right. The technics has a bus control system which involves little plugs sticking out at the top an bottom of each piece, which transmit power, signal and control info - no wires needed between components, and each component is also connectable with normal RCA plugs - neat. The microcontroller may be being used for switching inputs, EQ in and out, etc?

Hi,

http://www.necel.com/nesdis/image/X10088EJ5V0SG00.pdf

Not exactly what you are looking for. Maybe it helps. But many numbers of NEC are not on the internet. If you call NEC they are sometimes helpful to provide a paper datasheet.

Cheers
