TDA1541A R1 question

Ruach · 2nd September 2005, 04:25 AM

Just a quick question guys as I am not able to locate a copy of the datasheet for the TDA1541A R1 chip.

Is the R1 chip the same as any TDA1541A chips?

I am planning to replace a TDA1541A in a cdp with that of the R1 version.

Thanks

not a wise move.
R1 is lower grade.

True

I had a couple of them. They always sounded worse than plain "A".

It has always been assumed that "R1" stood for relaxed specs/performance. Of course, remember this comes from someone who hates all of them.

hmmmm...

according to Philips' datasheet, the R1 version has slightly better distortion figures at -60dB (-43dB instead of -42dB), all other parameters being equal.

Cheers,

Thanks guys for your comments.

I got the chip number wrong.

It is TDA1541 R1 , date coded 87

The dac in my Arcam cdp is a TDA1541A, date coded 95, made in Taiwan.

Will the R1 sound better than the MIT (made in Taiwan) version?

I am inching my diying interest in the direction of the TDA1541 and there is so much stuff so learn.

Interesting............don't recall having seen a "non-A" chip with an R1 as a suffix. Date sounds about right, though.

The non-A version of the TDA1541 is right in front of my desk right now.

I am not able to find any info on it though.

What direction do you think should go someone who is tired of TDA1541A sound, doesn't like non-os but don't want anything sounding inferior to it?
