ADS1247: Current part : ADS1147IPWR Suggested part : ADS1247IPWR

Part Number: ADS1247
Other Parts Discussed in Thread: ADS1147

After comparing current part with suggested part, we found that major difference is in ADC resolution .

 

Current part comes with 16 bit resolution while proposed part comes with 24bits.

Apart from that almost all electrical parameters are common .

 

Can you please confirm about compatibility to use 24 bit ADC directly in place of 16 bit .

 

Do we need to modify our firmware ?

  • Hi Saurabh,

    The ADS1147 and ADS1247 are functionally and parametrically similar. There are some specifications that might be different between the two devices e.g. INL, but this is mainly due to the different resolutions

    The major difference between the two devices is the bit-width, where the customer will have to issue additional SCLKs to read back data. Therefore, some minor FW modifications are required
