ICL7137 Low Power, 3½ Digit A/D Converter Data sheet
■The Maxim ICL7137 is a monolithic analog to digital converter with all the necessary active devices to directly interface with a light emitting diode (LED) display. Excluding the Led display current, the ICL7137 supply current is under 200uA, 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 environments. The true differential input and reference are particularly useful when making ratiometric measurements (ohms or bridge transducers),and the zero-integrator phase in Maxim's ICL7137 eliminates overrange hangover and hysteresis effects.Finally, this device offers high accuracy by lowering rollover error to less than one count and zero reading drift to less than 1μV/℃.
