 23 Feb 2006 13:37 Opamp ADC circuit to replace the ADC0820? |

Is there any circuit to replace the ADC0820
(what I mean is the equivalent opamp ADC circuit that would function as the same as the ADC0820)

the adc0820 contains more than 30 comparators and other logic and control ckt so u can just use your opamps ckt instead of a single chip adc0820, other chip u can use is ADC0800 series which are easily available and cheaper, but it is slow 100us
and adc0820 has 1.5us conversion time.
for more details the datasheet from national site can be downloaded from this link

bye for now
keep posting
