Product Overview

The ICL7137CPL+ is a low power, 3.5digit analogue to digital converter (A/D) in 40 pin DIP package. It is a monolithic converter with all necessary active devices to directly interface with LED display. Excluding LED display current, the ICL7137 supply current is under 200µA making it suitable for battery operation. Versatility 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 and zero integrator phase in ICL7137 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.
  • Operating temperature range from 0°C to 70°C
  • First reading recovery from overrange
  • Zero input gives zero reading
  • 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
  • V+ supply current of 70µA (does not include LED current)
  • Segment sinking current of 8mA
  • Common mode rejection ratio of 30µV/V
