7107 is a monolithic analog to digital converters (ADCs) with very high input independence and requires absolutely no external display drive circuitry. It can drive a common anode 4 digit 7 segment display directly. It has a resolution of 3+� bits which means it can display digital value from 0 to 1999. It uses a dual-slope ADC so an applied voltage is compared to reference voltage and then approximated to find the applied voltage. These features make it perfect for users who want to display the measured voltage without any MCU and programming. Users simply need to hook up a wire with a 7-segment display with an output of the IC and they will be ready to display the measured voltage.

The IC has inherent features of versatility and accuracy. The dual-slope ADC technique automatically rejects interference signals and the true differential input and reference are particularly important useful while making ratiometric measurement (ohms and bridge transducers).
