I have DAC AD5689R 16bit , slew rate 1.6V/us (Gain 2x) , complete with an external analog switch 10V/us.
I need to extend the slew rate , programmable with min 8 step for example
1V/ms
5V/ms
10V/ms
50V/ms
0,1V/us
0,5V/us
...
Something should probably be done digitally over DAC, but something requires an external hw .
I devised analog switch any as DG211 and connect capacitors.
Advise some funny solution or appnote dealing with this problem?
