LSB means least significant bit and changes depending on the voltage range. See the Programmable Gain section for the LSB size.

3

All ac accuracy 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

This is the output from the internal band gap reference.

5

There is no pipeline delay. Conversion results are available immediately after a conversion is complete.

VSSH). Note that the specified operating input voltage of any input pin requires 2.5 V of headroom from the VDDH and VSSH supplies; therefore, (VSSH + 2.5 V) ≤

INx/COM ≤ (VDDH − 2.5 V).
