PRODUCTION DATA
The ADS127L11 provides the ability to calibrate offset and gain errors by using user-programmable offset and gain correction registers. As shown in Figure 8-28, the 24-bit offset correction value is subtracted from the conversion data before being multiplied by the 24-bit gain correction value. Output data are rounded to the final resolution (16- or 24-bit) and clipped to +FS and –FS code values after the scaling operation.
Equation 18 shows how conversion data are calibrated:
