    Best means for a dual vref?

    Fair enough. Thank you. Any ideas on how to get rid of the offset issue? I have tried multiple solutions, but this has worked the best sofar

    What's the difference between 8 & 32

    The number of bits refers to the size of the data pipe. C will probably hide this from you this, but if you are programming with assembly, you will find if you need to add a 32 bit number to another 32 bit number, you will need far fewer instructions to do so on the 32 bit uC vs the 8 unless it...

    Rigol or Atten oscilloscopes

    I have the Rigol. It is quit nice and  modifiable to act as a 100Mhz DSO. You can see a good review of it on Dave's EEV Blog. I believe he said Agilent designed it. I don't know anything about the other scope.. the wider display looks nice

    Best means for a dual vref?

    This circuit takes the output of a dac (min of 0v and max of ~4.096v.. [depending on % off]) that comes in through the Y port and creates a signal used to drive a galvo amplifier. The galvo amplifier requires a balanced bipolar differential signal between -10v and 10v. In this circuit the ILDA...

    Best means for a dual vref?

    I have a circuit that needs two voltage references, lets say 5v and 2.5v What would be the best way to ensure the lower value was exactly 1/2 the value of the higher voltage (e.g. accounting for % tolerances on the 5v voltage reference)? Temperature variances won't be too much of a concern, but...
