Would it be "okay" to use a voltage divider from a regulated 5v source as a reference voltage for a 339 comparator since its input impedance is ideally infinite? Also is there anything else i need to consider if i just want to output a "high" if the input is below the reference, just the Vin the Vref and a pullup resistor on the output to get TTL level output?
thanks for any suggestions or comments
