8XC51SL/LOW VOLTAGE 8XC51SL
Sample WindowD
Begins when the sample capaci-
tor is attached to a selected channel and ends when
the sample capacitor is disconnected from the se-
lected channel.
Successive ApproximationD
An A/D conversion
method which uses a binary search to arrive at the
best digital representation of an analog input.
Temperature CoefficientsD
Change in the stated
variable
per
degree
centrigrade
change. Temperature coefficients are added to the
typical values of a specification to see the effect of
temperature drift.
temperature
Terminal Based CharacteristicD
An actual charac-
teristic which has been rotated and translated to re-
move zero offset and full scale error.
V
CC
RejectionD
Attenuation of noise on the V
CC
line to the A/D converter.
Zero OffsetD
The difference between the expected
and actual input voltage corresponding to the first
code transition.
DATA SHEET REVISION SUMMARY
