<DIV>What is quality of possible developed 16 bits DAC for DC level
generation with single pole RC low pass
filter? </DIV></FONT></BLOCKQUOTE></DIV>

<DIV>================================================</DIV>
<DIV>The counter can count 20 million clocks a sec. You get a 16 bit count 305
times a sec, so if you have an RC at .1Hz, you'll be 20db down at 1hz, 40db down
at 10hz, 60db down at 100hz. Not quite the 90db you need to have 16 bit
resolution</DIV></FONT><BR><BR><BR><DIV><FONT style="color: black; font: normal 10pt ARIAL, SAN-SERIF;"><HR style="MARGIN-TOP: 10px">See what's free at <A title="http://www.aol.com?ncid=AOLAOF00020000000503" href="http://www.aol.com?ncid=AOLAOF00020000000503" target="_blank">AOL.com</A>. </FONT></DIV></BODY></HTML>
