With the ±4.096 V input range, one LSB is 250 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 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. 4 Tested fully in production at fIN = 1 kHz. |
