Does anyone know of any old-school function generator ICs (similar to the ICL8038 or XR2206) that are still on the market? (i.e. not obsolete / NFFD – I'm not interested in scouring the globe for old inventory)
I'm aware of digitally-programmable parts that use I2C / SPI, but am looking for something that won't involve adding a micro to a legacy design.
I'm looking primarily for an IC that will output a triangular waveform at low frequency (640Hz). The XR2206 was the original part in the application which is now obsolete. The frequency can be adjusted a small amount from an external input (+/- 50Hz or so).
Exar has obsoleted most (all?) of their function generator parts:
update:
The product has passed into obsolescence and the assigned engineer is no longer with the company. The question is now moot.

This would seem to be similar to the XR2206 :)
