SBASAK4B March 2023 – April 2024 ADS127L21
PRODUCTION DATA
The ADS127L21 offers offset and gain calibration by the user offset and gain calibration registers. As shown in Figure 7-34, the 24-bit offset calibration value is subtracted from the conversion data before being multiplied by the 24-bit gain calibration 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 20 shows how conversion data are calibrated:
