3 1/2 Digit, LCD/LED Display, A/D
Converters
FN3082.8
Features
• Guaranteed Zero Reading for 0V Input on All Scales
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 autozero 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.

NOTES:
1. “R” indicates device with reversed leads for mounting to PC board underside. “S” indicates enhanced stability.
2. Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
