Description
The Intersil ICL7106 and ICL7107 are high performance, low
power, 31/2 digit A/D converters. Included are seven seg-
ment decoders, display drivers, a reference, and a clock.
The ICL7106 is designed to interface with a liquid crystal dis-
play (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 10µV, zero drift of less than 1µV/oC, 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.
