1
LSB means least significant bit and changes depending on the voltage range.
2
The common-mode voltage (V
CM
) 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 range (FSR) and tested with an input signal at 0.5 dB below full scale, unless otherwise noted.
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).
