| SD8331 | The SD8331 series consists of ultra-low-power mixed-signal processors with peripherals for electricity-meter applications. It integrates an analog front end, fixed-function DSP, an enhanced 8052 MCU core, RTC, and LCD drivers in one device. The measurement engine calculates active, reactive, and apparent energy and measures voltage, current RMS, and frequency. | LQFP (7×7) | |
| SD7413 | SD7413 is a highly integrated power and energy monitoring analog front end (AFE) IC for electricity metering. It includes an 8-channel ADC and programmable DSP for metering, power protection, and master/slave applications. | 4x4 QFN24 | |
| SD7211 | SD7211 is a highly integrated power and energy monitoring analog front end (AFE) IC for measuring electricity-related data. It includes an 8-channel ADC and programmable DSP for metering, power protection, and master/slave applications. | 4×4 QFN24 |
