Description
The Harris ICL7106 and ICL7107 are high
performance, low power 3 1/2 digit A/D converters.
Included are seven segment decoders, display drivers,
a reference, and a clock. The ICL7106 is designed to
interface with a liquid crystal display (LCD) and
includes a multiplexed backplane drive; the ICL7107
will directly drive an instrument size light emitting
diode (LED) display.
The ICL7106 and ICL7107 bring together a
combination of high accuracy, versatility, and true
economy. It features auto-zero to less than 10mV, zero
drift of less than 1μV/°C, input bias current of 10pA
max., and rollover error of less than one count. True
differential inputs and reference are useful in all systems,
but give the designer an uncommon advantage
when measuring load cells, strain gauges and other
bridge type transducers. Finally, the true economy of
single power supply operation (ICL7106), enables a
high performance panel meter to be built with the
addition of only 10 passive components and a display.
