Hi,

I have a question about the channels of an ADC. I was trying to make a multichannel analyser with a successive approximation ADC (ADCS7477) for a spectrometry experiment. The ADC has a 10 bit resolution.
Does this mean that there are 1024 channels (210)?
 

Hi,

it seems you are not aware of the basic theory of operationof an ADC.

Please study the operation of an ADC.

To your question.
No. It doesn´t have 1024 input channels. How could this be with just 6 terminals.
10 bit resolution means it can measure 2^10 different levels of voltage within it´s full scale input voltage range (in this case VDD).

if you connect the ADC chip with a 2.7v V_DD, then the resolution is
Code:
2.7 / 2^10 = 0.0026

when the ADC detects a anolog voltage of 0.0026, it'll convert it into its digital form: 10'b00_0000_0001.

update:
Code:
Code transitions occur midway between successive integer LSB values

The datasheet has all the information you need.
