Tested with an input signal at 0.5 dB below full scale, unless otherwise specified. 2 LSB means least significant bit. With the 5 V input range, 1 LSB is 76.3 µV. 3 See the Terminology section. These specifications include full temperature range variation, but not the error contribution from the external reference. |
