Hi, I was wondering what is the purpose of connecting 0.01 micro farad capacitor across pin 30 and pin 31 of the circuits http://www.electro-tech-online.com/custompdfs/2012/07/fn3082.pdf(page 11 to page 12 every typical circuit does connecting it) ? I have tried to read through the datasheet...

I get it now, Thank you so much, you guys are really helpful.

I was wondering what are the uses of 200mV scale in voltmeter? I mean isn't it too small for most applications? but it seems to me every meter has such small scale ,so I was wondering what is their actual usage?

Hi, Thanks for your advice indeed, and no, I have not got pins 30 and 32 joined together but I have joined the pin 30 to the same ground as the IC. The problem was solved, it is because of the 'leg', I don't know what it is called, its function is that we can solder the legs and put whatever...

I'm building ICL 7107 digital voltmeter with 200mV full scale as Figure 12 (page 11) on http://www.intersil.com/data/fn/fn3082.pdf. Here is the problem I'm facing: it shows random numbers, sometimes showing 1666, and it has no effects even when I try to calibrate by adjusting the...
