1 See the Terminology section. 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 = 2.5V; TA = –40°C to +85°C, unless otherwise noted.
