4x24-bit sigma-delta ADC — what it means for metering designs
The MSP430F6746IPEUR: The four 24-bit sigma-delta converters sample voltage and current phases simultaneously. The LCD driver handles segment displays directly.
Obsolete — sourcing reality
Temperature grade and environment
Rated for -40°C to 85°C, the part fits outdoor meter cabinets, substation enclosures, and factory-floor instrumentation panels. The 128-LQFP (20x14 mm) package is a standard footprint for this I/O count; the 90 GPIOs map well to a split of sensor inputs, display segments, and communication port control lines.
