8.3.1.2 Full-Scale Voltage (VFS) Adjustment

Input full-scale voltage (VFS) adjustment is available, in fine increments, through FS_RANGE. All inputs are set to the same full-scale voltage setting. The available adjustment range is specified in the DC Specifications table. Larger full-scale voltages improve SNR and noise floor (in dBFS/Hz) performance.
