ADS124S06: How to convert codes to bits?

Part Number: ADS124S06

Hi there, 

We are using ADS124S06IPBS for Bridge sensor.

In ADS124S08EVM user guide,

Mentioned as noise codes are converted into bits (i.e.,) 117.7 codes into 6.803 bits.

How do we convert this? Is there any formula for this conversion.

Kindly give your answers on this.

Thanks & Regards,


  • Hi Sneha.K,

    This is a conversion from base10 to base2.  You can use long division to determine you many times 2 divides into the decimal number.  However it is usually easier with a log conversion such as log2 (decimal number).  However many calculators will not make this conversion directly (unless you can find one online).  You can take the log10(decimal number) / log10(2).  

    For this example we can take log10(117.7) / log10(2) = 2.07 / 0.301 = 6.87 which is now equivalent to the number of bits.  To verify your calculation you simply convert back to decimal 2^6.87 = 117 codes.  Here we see some rounding error, but it is close enough.

    Best regards,
