1
LSB means least significant bit and changes depending on the voltage range. See the Programmable Gain section for the LSB size.
2
The common-mode voltage (V
CM
) range for a PGIA gain of 0.16 or 0.2 is 0 V.
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.
6
The differential input common-mode voltage (V
CM
) range changes according to the maximum input range selected and the high voltage power supplies (VDDH and
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).
