FN3084.5
3 1/2 Digit, Low Power, Single Chip A/D
Converter
The ICL7126 is a high performance, very low power
3 1 / 2 -digit, A/D converter. All the necessary active devices
are contained on a single CMOS IC, including seven
segment decoders, display drivers, reference, and clock. The
ICL7126 is designed to interface with a liquid crystal display
(LCD) and includes a backplane drive. The supply current of
100 μ A is ideally suited for 9V battery operation.
The ICL7126 brings together an unprecedented combination
of high accuracy, versatility, and true economy. It features
auto-zero to less than 10 μ V, zero drift of less than 1 μ V/ o C,
input bias current of 10pA maximum, and rollover error of
less than one count. The versatility of true differential input
and reference is useful in all systems, but gives the designer
an uncommon advantage when measuring load cells, strain
gauges and other bridge-type transducers. And finally the
true economy of single power operation allows a high
performance panel meter or multi-meter to be built with the
addition of only 10 passive components and a display.
The ICL7126 can be used as a plug-in replacement for the
ICL7106 in a wide variety of applications, changing only the

NOTES:
1. Intersil Pb-free 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-020C.
