LSB means least significant bit. With the 5 V input range, 1 LSB is 76.3 μV.
See the Terminology section. These specifications do include full temperature range variation, but do not include the error contribution from the external reference.
All specifications in dB are referred to a full-scale input FSR. Tested with an input signal at 0.5 dB below full scale, unless otherwise specified.
