The ADC used here is a dual slop ADC, so the applied voltage is compared with a reference voltage and then is approximated to find the applied voltage. The speciality of this IC is that it has an in-built 4-digit 7-segment display driver inside it. So to display the measured voltage we simply have to hook up 7-segment display to the output of the IC and everything is ready. The digital output can vary from where each digit is displayed on a single 7-segment display. So if you are trying to measure voltage and display them on a 7-segment display without the use of MCU or programming then this IC might be the right choice for you. Using ICL is pretty straight forward, we just have to provide the reference voltage and set the internal clock for the ADC conversion to take place and we are all set.

It is identical to the ICL except that the regulated supply and back. It is identical to the ICL except that the regulated supply and back ,. It is identical to the ICL except that the regulated , reversed also, if desired. It is identical to.
In , negligible DC voltage exists across the segments. In the ICL, an internal , across the segments. They have very high input impedances and require no external display , whereas the ICL will directly drive a common anode light emitting diode LED display.
In the , negligible DC voltage exists across the segments. As the , converters. Q: How much power supply current is needed to operate the ICL? A: The , of display segments lighted. The ICL without display current requires typically 1. In Figure 8, an , directly drive a non-multiplexed liquid crystal display LCD whereas the ICL will di rectly drive a , and ICL , elimi nating overrange hangover and hysteresis effects.
