With the 5 V input range, 1 LSB is 76.3 µV. 2 See the Terminology section. These specifications include full temperature range variation, but not the error contribution from the external reference. 3 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. |
