These specifications include full temperature range variation but do not include the error contribution from the external reference. 2 All specifications in dB are referred to a full-scale input, FS. Tested with an input signal at 0.5 dB below full scale, unless otherwise specified. VDD = 2.7 V; VREF = 2.5 V; TA = −40°C to +85°C, unless otherwise noted. Table 4.
