Digit LCD/LED Display A/D Converter
PRODUCT DESCRIPTION
The ICL7106 and ICL7107 are high performance, low power, 3
�½
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. 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.
Display-hold, low-battery flag, integration and de-integration status flags are four additional features which are available
in the 44-pin package.
