Overview
Description
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.

How can I use the ICL7106 to display voltages higher that 2V?
Question:I am planning on building a DVM incorporating the ICL7106 as my LCD Driver. The datasheet and application notes imply that the range is only 200mV to 2V. But the device will drive a display up to 1000 (i.e. 3 1/2 Digits). So if I want ...

How do you implement input protection on the ICL7106?
... voltmeter, for example, what happens if the user measures 200 volts while the 200 millivolt input is selected? Answer: The analog input pins of the ICL7106 have parasitic devices to the supplies that provide some protection, provided the input current is limited to +/-100uA as indicated in Note 6 ...
