Va ∈ [0 - 10]
8-bit resolution
during conversion 10us
REQUIRED:
* 1LSB=?,1MSB=?,FSR=?, quantization error=?
* Vi=? if you are obtained 00110011?
* if Vi=0.25V how is the binary code output?
* how to be gain amplifier to convert Vi with the maximum resolution,calculate R1 and R?
* Maximum sampling rate, but the maximum frequency of the input signal that can be converted with the converter?

1 LSB = 0.0196078431372549

1 MSB = 2.509803921568627

if Vi = 0.25V then binary value will be 00001100

Re: problem to be solved

Don't think so:

1 LSB = 10V / 28 = 10V / 256 = 0.0390625V

1MSB = 128 * 0.0390625V = 5V

if Vi = 0.25V then binary value will be = 00000110 = 6LSB

2b00110011 = 51 * 0.0390625V = 1.9921875V

Sorry I have calculated for 5V
