NOTES:
1. Absolute maximum rating specifies the values beyond which the device may be damaged permanently. Exposure to
ABSOLUTE MAXIMUM RATING conditions for extended periods may affect reliability. Each condition value is applied
with the other values kept within the following operating conditions and function operation under any of these conditions
is not implied.

.AINT = REFBOT ~ REFTOP
.AINC = REFTOP ~ REFBOT
.1
LSB
D
= (REFTOP - REFBOT)/1024
and for Single Input
.AINT = (REFTOP + REFBOT)/2 - (REFTOP - REFBOT) ~ (REFTOP + REFBOT)/2 + (REFTOP - REFBOT)
.AINC = (REFTOP + REFBOT)/2
.1
LSBS = 2(REFTOP - REFBOT)/1024
2. Using Differential Input Mode : AINT = 0.65 ~ 1.15, AINC = 1.15 ~ 0.65

LSBD = (REFTOP - REFBOT)/1024 = 0.976562mV
