[sdiy] Appearance of many SSM2300 chips

[Tom Wiltshire]

Hi all,

Has anyone else noticed the sudden appearance on eBay of loads of SSM2300 (sample and hold multiplexer) chips?

Periodically I check eBay to see if anyone has anything interesting, and I'm sure that last time I looked there weren't the same loads of SSM2300s that I see this time. Has someone found a secret stash of thousands and suddenly started dumping them or something?

Secondly, is such a chip actually useful any more? It seems to me that it probably isn't. Using a single DAC with multiplexers is a bit redundant in this age of many multichannel DACs, and this particular multiplexer doesn't seem to have sufficient accuracy to make you have second thoughts ("High accuracy: 8-bits absolute, 12 bit linearity" they say in the datasheet).
