3 1/2 Digit, Low Power, Single Chip A/D Converter

The ICL7126 is a high performance, very low power

Features

3 / -digit, A/D converter. All the necessary active devices

• 8,000 Hours Typical 9V Battery Life

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A is ideally suited for 9V battery operation.

• Guaranteed Zero Reading for 0V Input on All Scales

• True Polarity at Zero for Precise Null Detection

• 1pA Typical Input Current

• True Differential Input and Reference

The ICL7126 brings together an unprecedented combination

of high accuracy, versatility, and true economy. It features

auto-zero to less than 10V, zero drift of less than 1V/ C,

• Direct LCD Display Drive - No External Components

Required

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.

• Pin Compatible With the ICL7106

• Low Noise - Less Than 15V

P-P

• On-Chip Clock and Reference

• Low Power Dissipation Guaranteed Less Than 1mW

• No Additional Active Circuits Required

• Pb-Free Available (RoHS Compliant)

The ICL7126 can be used as a plug-in replacement for the

ICL7106 in a wide variety of applications, changing only the

passive components.

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.
