The Maxim ICL7135 is a high precision monolithic41/2 digit A/D converter. Dual slope conversion reliabilityis combined with ±1 in 20,000 count accuracy anda 2.0000V full scale capability. It features high impedancedifferential inputs, nearly ideal differential linearity,true ratiometric operation, auto zero and auto-polarity.The multiplexed BCD outputs and digit drivers provideeasy interface to external display drivers like the MaximICM7211A. The only other external components neededto make precision DVM/DPMs are a reference and aclock. For more complex systems the BCD outputs areenhanced by Active-Low STROBE, OVERRANGE, UNDERRANGE,RUN/Active-Low HOLD and BUSY lines providing easy interface tomicroprocessors and UARTs. This interfacing capabilitymakes the ICL7135 an ideal device for use in microprocessorbased data acquisition and control systems.The ICL7135 has auto-zero accuracy better than 10µV,zero drift of 0.5µV/°C, input bias current of 10pA max. androllover error of less than 1 count.ApplicationsCurrentMaterial ThicknessPressureResistanceSpeedTemperatureVoltageWeight

The ICL7665 warns microprocessors (µPs) of overvoltage and undervoltage conditions. It draws a typical operating current of only 3µA. The trip points and hysteresis of the two voltage detectors are individually programmed via external resistors to any voltage greater than 1.3V. The ICL7665 will operate from any supply voltage in the 1.6V to 16V range, while monitoring voltages from 1.3V to several hundred volts. The Maxim ICL7665A is an improved version with a 2%-accurate VSET1 threshold and guaranteed performance over temperature.The 3µA quiescent current of the ICL7665 makes it ideal for voltage monitoring in battery-powered systems. In both battery- and line-powered systems, the unique combination of a reference, two comparators, and hysteresis outputs reduces the size and component count of many circuits.ApplicationsµP Voltage MonitoringBattery-Backup SwitchingHigh/Low Temperature, Pressure, Voltage AlarmsLow-Battery DetectionOver/Undervoltage ProtectionPower Supply Fault MonitoringPower-Fail and Brownout Detection

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
