The ADS1230REF is a reference design for the ADS1230 20-bit, delta-sigma analog-to-digital converter? (ADC). It contains all the circuitry and user interface elements needed for a weigh-scale digitizer, and is?? meant as an example of good design for a basic weigh-scale system. The ADS1230REF is also suitable?? for general evaluation of the ADS1230 device.
