I have a question, but i also want the following answer if possible " YES IT's FINE LG".
In most R 2R ladder DACS there is often a opamp at the end, if the implication isnt driving much (in this case a sub mA coil on a meter), is it ok to do away with the Opamp? The Resistors will be 10K and 5K or might end up 20K and 10K, Please see above correct answer in Bold
.
Other answers welcome but likely to make me grumpy
Thanks
