ICL7136CPL+ Datasheet PDF - Maxim Integrated

●The ICL7136CPL+ is a low power, 3.5 digit monolithic analogue to digital converter (A/D) converter in 40 pin DIP package. This ADC has very high input impedance. Onboard active components include segment drivers, segment decoders, voltage reference and clock circuit. Versality and accuracy are inherent features of this converter. The dual slope conversion technique automatically rejects interference signals common in industrial environment. The true differential input and reference are useful when making ratiometric measurement (ohms and bridge transducer) and zero integrator phase in ICL7136 eliminates overrange hangover and hysteresis effects. This device offers high accuracy by lowering rollover error to less than one count and zero reading drift to less than 1µV/°C. It can be used in wide range of digital panel meter applications and measuring and display of pressure, voltage, resistance, temperature, conductance, current, speed and material thickness.
