Product Summary

The ICL7107 is a high performance, low power, 3x1/2 digit A/D converter included seven segment decoders, display drivers, a reference, and a clock. The device will directly drive an instrument size light emitting diode (LED) display. During signal integrate, the auto-zero loop is opened, the internal short is removed, and the internal input high and low are connected to the external pins. The ICL7107 then integrates the differential voltage between IN HI and IN LO for a fixed time. This differential voltage can be within a wide common mode range: up to 1V from either supply.

Parametrics

ICL7107 absolute maximum ratings: (1)Supply Voltage, ICL7107, V+ to GND:6V; ICL7107, V- to GND:-9V; (2)Analog Input Voltage (Either Input): V+ to V-; (3)Reference Input Voltage (Either Input):V+ to V-; (4)Clock Input, ICL7107:GND to V+; (5)Temperature Range:0℃ to 70℃; (6)Maximum Junction Temperature:150℃; (7)Maximum Storage Temperature Range:-65℃ to 150℃; (8)Maximum Lead Temperature (Soldering 10s):300℃.
