negative voltage reference

HOW TO DO THAT!


thanx in advance!
 

negative reference voltage

hi,

what technology does it use? TTL or ECL like that. i think only ECL logic has a negative reference voltage. for it to not enter the saturation region. that is all i am able to resolve abt this problem. but, anyother person could help with this question. seems a good question.

regards,
Arun.
 

negative voltage reference ic

I think you could use an OP Amp to invert the voltage, but this solution will drop more current from the supply and you need positive and negative supply.

best regards
 

negative output voltage reference

This is very simple.
Just connect a MAX826 to your LM385 output:

Be aware, there is an error in this application note.
The application note is about MAX828, but at the schematic it says MAX826.
Just use a MAX828, there is no IC called MAX826, it's just a typing error.

positive and negative voltage reference

You can also use these devices similar to Maxim MAX828:
