ICL7106 / 7107

Description

Features

The ICL7106 and ICL 7107 are high performance, low power

3-1/2 digit A/D converters. Included are seven segment

decoders, Display drivers, a reference and a clock. The ICL

7106 is designed to interface with a liquid crystal display

(LCD and includes a multiplexed backplane drive; the ICL

7107 will directly drive an instrument size light emitting diode

(LED) display.

The ICL7106 and ICL 7107 bring together a combination of

high accuracy, versatility and true economy. True differential

inputs and reference are useful in all systems, but give the

designer advantage when measuring load cells, strain gauges,

and other Bridge type transducers.

By providing the true economy of a single power supply

operation, the ICL7106 enables a high performance panel

meter to be built with the addition of only 10 passive

components and a display.
