3位A / D转换器 3 Digit A/D Converter
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.
