Abstract :
The A/D converter applied to electric power meter needs wide dynamic range. We propose Smart A/D Converter System which uses D/A converter, operational amplifier and analog switches, calibrates automatically and has wide dynamic range. We evaluated this proposal by general purpose MCU and got good result.
