ICL7116CPL+

The ICL7116CPL+ is a 3½ digit ADC with display hold in 40 pin DIP package. This integrating ADC has very high input impedances and directly drives LCD display. 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 is particularly useful when making ratiometric measurements (ohms or bridge transducers). Analog Devices has added a zero-integrator phase to the ICL7116, eliminating overrange hangover and hysteresis effects. Finally, this device offer high accuracy by lowering rollover error to less than one count and zero reading drift to less than 1μV/°C. This device can be used in a wide range of digital panel meter applications.

• Supply voltage range is 0V to 9V
