ICL7136CPL+

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.

• Zero input gives zero reading
• Operating temperature range from 0°C to 70°C
• Power dissipation of less than 1mW, 9V battery with 3000hr battery life
• First reading recovery from overrange
• Low noise of 15μVp-p without hysteresis or overrange hangover
• True differential reference and input
• Low power CMOS design and conversion rate of 0.0025Ksps
• Superior device due to reduced power consumption
• Directly drives nonmultiplexed LCD display without requiring external display drive circuitry
