Millivolt Circuit ICL7129
My application is to calibrate some instruments with help of this source. I've studied your circuit earlier also., but I want a battery operated mV source.upto 100mV full scale which is portable but still very accurate.
I've constructed some prototype tell me how can I send you the schematic? (file format e.g. jpg, *.tiff, *.bmp etc..., i'm using Orcad 9.2 and Express PCB Schematic softwares for Schematics).
Also I need a 4 1/2 digit LCD display for this circuit(Or any good one). I'm referring ICL7129/ Max7129 IC datasheet for this. Do you have any 2v DVM/ DPM circuits, can you please email me the same! ...please!

I have completed the millivolt circuit, but I need some more information regarding using ICL7129 for driving a 4 1/2 digit LCD for displaying the
