ICL7107CQH Datasheet PDF - Maxim Integrated

General Description

●The Maxim ICL7106/ICL7107 are monolithic analog-to-digital converters (ADCs). They have very high input impedances and require no external display drive circuitry. On-board active components include polarity and digit drivers, segment decoders, voltage reference and a clock circuit. The ICL7106 will directly drive a nonmultiplexed liquid crystal display (LCD), whereas the ICL7107 will directly drive a common anode light emitting diode (LED) display.
