LCD Drivers 3 1/2 Digit A/D Converter

The Maxim ICL7126 is a monolithic analog to digital converter with very high input impedance. On-board active components include segment drivers, segment decoders, voltage reference and a clock circuit. The ICL7126 directly drives a non-multiplexed liquid crystal (LCD) display, requiring no external display drive circuitry. Significantly reduced power consumption makes the ICL7126 a superior device, especially for portable systems.Versatility and accuracy are inherent features of this converter. The dual-slope conversion technique automatically rejects interference signals common in industrial environments. The true differential input and reference are particularly useful when making ratiometric measurements (ohms or bridge transducers), and the zero-integrator phase in Maxim's ICL7126 eliminates overrange hangover and hysteresis effects. The Zero Integrator phase also allows the use of larger auto zero capacitors reducing noise further. Finally, this device offers high accuracy by lowering rollover error to less than one count and zero reading drift to less than 1μV/°C.ApplicationsConductanceCurrentMaterial ThicknessPressureResistanceSpeedTemperatureVoltage

The Maxim ICM7211 (LCD) and ICM7212 (LED) four digit, seven segment display drivers include input data latches, BCD to segment decoders, and all level translation and timing circuits needed to drive non-mulitplexed displays.Both the ICM7211 and ICM7212 are available in two data input configurations: a mulitplexed BCD interface version and a microprocessor interface version. The multiplexed BCD interface version has four BCD data inputs and four separate digit strobes. The microprocessor interface versions, designated by an 'M' suffix, have four chip selects or WRITE inputs.The ICM7211 and ICM7212 decode the BCD data via an onboard character font ROM. There are two different character fonts available, hexadecimal and Code B.ApplicationsDigital Panel DisplaysIntelligent InstrumentsMicroprocessor-to-Visual CommunicationRemote Display Units
