1 LSB means least significant bit. With a 5 V input range, 1 LSB = 305.2 μV.

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

3 All specifications in decibels are referred to a full-scale input, FS. Tested with an input signal at 0.5 dB below full scale, unless otherwise specified.

4 With all digital inputs forced to VIO or GND as required.

5 During acquisition phase.
