ICL7106/7107
Descwrwipw.tDiaotanSheet4U.com
The ICL7106 and ICL7107 are high performance,low power 31/ 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. 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 he 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
display.
