The offset and gain calibration spans are defined as the range of offset and gain errors that the AD7853/AD7853L can calibrate. Note also that these are voltage spans
Temperature ranges as follows: A, B Versions, –40 C to +85 C. For L Versions, A and B Versions f
B Version f
Specifications apply after calibration.
SNR calculation includes distortion and noise components.
Sample tested @ +25 C to ensure compliance.

CLKIN @ DGND when external clock off. All digital inputs @ DGND except for CONVST, SLEEP, CAL, and SYNC @ DV
Analog inputs @ AGND.
and are not absolute voltages (i.e., the allowable system offset voltage presented at AIN(+) for the system offset error to be adjusted out will be AIN(–)
and the allowable system full-scale voltage applied between AIN(+) and AIN(–) for the system full-scale voltage error to be adjusted out will be V
This is explained in more detail in the calibration section of the data sheet.
