JAJSQE1 October 2024 ADS9212
PRODUCTION DATA
The ADS9212 features calibration logic to minimize gain error from the analog inputs. Enable gain error calibration for minimum gain error. Gain error calibration can be enabled by configuring the GE_CAL_EN1 (address = 0xD), GE_CAL_EN2, GE_CAL_EN3 (address = 0x33), and GE_CAL_EN4 (address = 0x34).
If gain error calibration is not enabled as shown in Table 6-5, the full-scale analog input ranges are increased by a factor of 1.024.
