Hello all,
Can a simple DAC like CS4334 to generate the output voltage starting from DC?
Can you sugest other type, beter but cheap and easy to use?
I need minimum 14-16 bits and DC to 100KHz bandwidth (slewrate over 5V/µsec for a 3V full scale).

audio DAC may have built in digital high pass
the CS4334 datasheet isn't clear - and the application diagram, specs are all for AC coupled use
in general audio DAC are poor at DC if they do it at all - there are many more DAC made for industrial/measurement/control which are intended for DC operation with complete DC accuracy specs

some example?
I need to not be very expensive and to have a simple implementation schematic.
I do not need a very precise DAC.

what V? what digital interface? - spi, spdf, parallel, usb...
today single chip uC with 10-12 bit DAC on a demo board for ~US$10 can be cheap for what you get
14-16 bits is precision for DC, going over ~12 bits real DC accuracy performance isn't so easy - lots of "onion peeling"
component Temp Coefficients, ageing, drift, Thermocouple effects, PCB layout, grounding...
for higher resolution the usual suspects today are ADI, TI, LTC all have DAC selection tools, app notes
