Hi,
i work on a range finder project. I need to help(source or suggestions) for displaying results of ADC( Analog to Digital Converter). I wonder how can i show ADC results on seven segment display. Is there any special integrated circuit for this situation?
Thanks

 

The easiest way is through a BCD-to-7segments Decoder (e.g. a 4511 IC)

 

There are also some ADC's that directly drive a digital display such as these.

I need to show results in 2 or 3 digits seven segment display(results are bigger than 9). Is it possible to construct multi-digit 7segment display with 4511 IC without using any microcontroller or microprocessor??

 

You can buy single chip ADC with BCD outputs.

For example, MAX1496 (pdf file).

You can also add a BCD counter to multiplex various digits. Like this...

I never tried it, so I'm not the best person to advice you; but you can find more info here: http://www.elecpod.com/circuit/lighting/2012/03287459.html

 

I will use 8 bit ADC. SO I think that BCD to 7segment display is useless for the project. Results must be shown from 0 to 255. So i have to use 3 seven segment display. For this reason, can you suggest me any integrated circuit to drive 7segment display according to 8 bit?

 

You can do it with three 74185 and three 7447 chips or with one PLA or MCU chip.

 

A 14-pin microcontroller could replace the ADC and all other chips, needing only 3 transistors for digit drivers to enable a 3 digit output. But then, you need to have the tools and experience to program it.

Thanks. I think your suggestion is more usefull for my project and the basic configuration is like this:

 

It is a 74185, not 74184.

 

May i know what is the model of adc u used for this circuit?
