I have used DAC1220 (Burr Brown from TI) (a pair simulating a load cell in a
functional tester). No huge issues. They are sigma delta but not audio -
they quote settling time as 2mS so your 1kHz may be a little high.



Hi Michael,

Thanks for the info.

I see they quote a settling time of 10 msec for 20 bit mode, and 2 msec
for 16 bit mode. Have you found it to really be 2 msec for 20 bit mode?
I see the settling time is for large signal changes, most likely I will
be making small changes in normal operation.
