How to treat AD7717 32bit ADC data in MCU

Hi All,


One of my customer would like to use AD7717 32bit ADC in his system.

His current system utilizes 24bit ADC.

He is now investigating to evaluate the AD7717 ADC by replacing current 24bit ADC.

In this approach, he has one concern about its software modification.

Current system (Precision HV Power Supply) is controlled by MCU.

His software compiler doesn’t have function library to support 64bit floating point data.

He think that by replacing the ADC from 24bit to 32bit will require 64bit floating point calculation.

He would like to hear from you about how to treat 32bit data in his software development tool.


Thank you for your help,
