GENERAL DESCRIPTION
The DASllS7/DASllS8/DASl1S9 are 1+/lS-/16-bit sampling
aualog-to-disital converters. They are ideally suited for use in
portable and remote data acquisition equipment where low
power consumption (6SOmWmuimum) and wide temperature
range (
2S"C
to +
85"C rated perfOrmaDcc) are required.
-
DASllS7IDASl1S8IDASllS9 provide guaranteed high accuracy
and high stability system pcrfOrmaDCC
essential to medical,
analytical and process control equipment: differential nonlinearity
of :O.OOIS% max and integral Donlincarity of :0.003% max
(DASllS8 and DASllS9); DOmissing codes guaranteed; pin
T.C. of :8ppmf'C max. zero T.C. of :80Jl.VIOC IOU and
differential nonlinearity T.C. of : IppmI"C max.
The wide dynamic range will enhancc the pcrfOrmaDCC critical
of
mcuurc:mentS in au and liquid chromatography, blood aualyzcrs,
distributed data acquisitioD in factory automatioD and power
sencrating equipment, and in automatic test equipment.
