All specifications in dB are referred to a full-scale input FS. Tested with an input signal at 0.5 dB below full-scale, unless otherwise specified.
LSB means least significant bit. With the ±5 V input range, one LSB is 152.6 μV.
See the Terminology section. These specifications do include full temperature range variation but do not include the error contribution from the external reference.
