Description
The Intersil ICL7116 and ICL7117 are high performance, low
power, 31/2 digit, A/D converters. Included are seven segment
decoders, display drivers, a reference, and a clock. The
ICL7116 is designed to interface with a liquid crystal display
(LCD) and includes a multiplexed backplane drive. The
ICL7117 will directly drive an instrument size, light emitting
diode (LED) display.
The ICL7116 and ICL7117 have all of the features of the
ICL7106 and ICL7107 with the addition of a HOLD Reading
input. With this input, it is possible to make a measurement
and retain the value on the display indefinitely. To make room
for this feature the reference low input has been connected
to Common internally rather than being fully differential.
These circuits retain the accuracy, versatility, and true econ-
omy of the ICL7106 and ICL7107. They feature auto-zero to
less than 10µV, zero drift of less than 1µV/oC, input bias cur-
rent of 10pA maximum, and roll over error of less than one
count. The versatility of true differential input is of particular
advantage when measuring load cells, strain gauges and
other bridge-type transducers. And finally, the true economy
of single power supply operation (ICL7116) enables a high
performance panel meter to be built with the addition of only
eleven passive components and a display.
