See the Analog Inputs section.

2

LSB means least significant bit. With the ±5 V input range, one LSB is 38.15 µV.

3

See the Terminology section. These specifications include full temperature range variation but not the error contribution from the external reference.

4

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.

5

Dynamic range obtained by oversampling the ADC running at a throughput fS of 400 kSPS, followed by postdigital filtering with an output word rate fO.

6

fIN1 = 21.4 kHz and fIN2 = 18.9 kHz, with each tone at −7 dB below full scale.
