Thanks Alan,

I forgot about Maxim and Analog Devices but have looked now and still
didn't find the right one. Need 3V, 16 bits or more, 8 pin SOIC,
cheap, lowish power, simple interface, available. DAC's for audio
don't need the DC accuracies required by other applications too.

Maxim have some nice new ones in a teeny tiny package but I'll try to
avoid that.

Thought there would be oceans of similar things around but apparently
not. I've found a source now for the TDA1545A in 8 pin DIP, which
might be OK. Princeton Technology make a compatible one (PT8215),
which leads me to think it might be kind of an industry standard.
