2013-11-01 TP3051J Telephone CODEC IC

P1030628S3Here’s a pic of a TP3051J telephone interface chip (CODEC and Filter).  Yes, a picture of the actual chip inside of the IC, after I popped the top off of it.  I have a lot of them so I figured that checking one out to see what was in it would be fun. The pic isn’t very good because it was taken through a magnifying glass which is not color corrected.

I’ve searched but can’t find much about it except the National datasheet.  All I know is that a lot of chip brokers will sell it if you submit a request for a quote.  I won’t do that, never ever again.  I got onto one email list of a BCBFH (search for BOFH) and they refused to take my email address off their mailing list.  I even called them but as is usual with crooked companies, they told me the sender of the email was not in, and to leave a message, which most likely was never even written down, or else tossed in the trash can.  I tried to report them to their ISP, but it didn’t help.  I finally put a filter in to trash any emails from them.  This is in clear violation of the U.S. CAN SPAM Act laws.  If anyone knows of a circuit that uses this chip, I would appreciate an email to my yahoo.com email address, acmefixer or leave a comment.
