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