Digital Panel Meter performs digital processing on or conversion and display of voltages, currents, other analog signals, and pulse signals. This project is based on popular ICL 7107 IC, which is analog to digital converter and has been designed to drive 7 segment LED display. The ICL7107 is high performance, low power, 3, 1/3 digit A/D converter. Included are seven segment decoders, display drivers, a reference, and a clock. This DPM project may be used in a wide variety of configurations Full scale reading of +/- 199.9mV (200mV)
