If the 8 bit ADC chip has 20 pins connection. How many output pins would an 8-bit ADC chip need for a BCD (Binary coded format) output?

 

........8?

 

2+4+4. Ducy?

 

Heh, well that was pretty easy. Thanks alot guys.

 

Well, looking at wiki, looks like the minimum is 4. With 8 you can do two decimal numbers.

 

What 8-bit ADC has a binary-coded output?

 

Not exactly. An "8-bit ADC" means 8 binary bits of resolution, or 256 states. This is independent of the data format, which could be serial (1 pin), binary (8 pins) or BCD (10 pins). All pin counts do not include strobes, clocks, etc.

Sorry, I meant to ask what 8-bit ADC has a BCD output?
