ADS1220IPW calibration

Other Parts Discussed in Thread: ADS1220

Hi,

How can ADS1220  be calibrated? The ADC is used in weighing applications using strain gauge load sensors.

Thanks,

Bob

    Hi Bob,

    The simplest method of calibration is a two point calibration.  You would then use the two points to measure the slope and apply to the successive measurement results.  In the end the formula looks like the line-slope formula where y = mx +b and m is the determined slope and b is the offset. The first point is a no load condition which is the 0 point for the measurement.  The second point would be a near or full-scale strain applied.

    If the calculation were specifically a load cell, then the calculation for determining the mass would be as follows:
