#114945 - It's an 8-bit converter Responding to: ???'s previous message |
Not knowing what his desired operating range is, I have to assume he wants to use the power supply at full scale. The '0808 and '0809 are 8-bit 8-channel converters. Therefore, if he can use 2.56 volts as a reference, then bumping up the supply to twice that will make manipulating the output unnecessary. If some other manipulation, e.g. conversion to milirads, picotons, gigaparsecs, is needed, he can do that in a table-lookup regardless of what his reference is. Of course, if his Vref is 5.12 volts, he can, and probably will want to discard his lsb anyway, since that's the uncertainty of this ADC anyway. (+/- 1 lsb, IIRC)
