S/H in DAC?

[lcsaszar]

Anybody used a Sample & Hold curcuit in a DAC (after the I/V conversion, in front of the output buffer)? I have a pair of National LF398AH, does it make sense to experiment with it? I attached the datasheet. Perhaps its acquisition time is too slow for this application.

S&H have been used to try to deglitch some instrumentation dacs to make them compatible with audio. OTOH, sigma-Delta dacs don't have the same glitch problems as some other types of dacs, however.
