My personal choice: MAX038 (no relation with the 8038), way better than any similar analog wave generators but discontinued long ago and never upgraded.
I know there are cheap DDS chips, but they require filters and control logic. This one goes from 100 KHz to 20MHz with just a bunch of parts.
Be careful of those sold online however as they're all fakes; this chip was killed well over a decade ago. I'm not aware of any clones yet, though I would welcome them if on par quality wise with the original.

- blattimwind 7y agoInteresting chip. It's quite literally almost an entire standard function generator on one chip, with a bandwidth far exceeding some similar chips. Whether it's actually better than those from the 80s, I'm not sure. Both HP and Philips used to use ASICs -- pretty much just matched diode arrays -- for their sine shaping, and that's about the most critical part in this kind of generator.
