ICL7106, ICL7107, ICL7107S FN3082
Rev 9.00
October 24, 2014 31/2 Digit, LCD/LED Display, A/D Converters
The Intersil 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. It features
auto zero to less than 10µV, 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. Features
• Guaranteed zero reading for 0V input on all scales
