ICL7135CQI+

Price range: $16.52 - $31.15

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
