Isn't LM723 the same part as UA723?
Aren't those just the new (TI) and old (National) part numbers for the same product?
Was LM723 some sort of TI "remake"(?) of the original National uA723?
I have a box of all kinds of 723s at home, from different manufacturers. I have some from
- National Semiconductor with LM Prefix
- Fairchild with uA Prefix
- SGS ATES with SG prefix
- ST with LM prefix
- RCA with CA prefix
- Harris with CA prefix
- Texas Instruments, some with LM and some with uA
- Siemens with TDB prefix
- Tesla with MAA prefix
- plus some more exotic stuff where I could not derive the manufacturer.
I simply dont know which ones were
- just relabellled
- built as a second source in a chip factory owned by the company
- cloned
In the last years, the major producers were National, ST and TI.
The spec sheet look almost identical among all 723 manufacturers.
Hope that helps. As said, I hope these chips wont survive me.
