Metering SoC with seven 24-bit sigma-delta ADCs
Its defining feature is the set of seven 24-bit sigma-delta analog-to-digital converters, purpose-designed for polyphase energy measurement — each phase voltage and current channel gets its own converter, so the firmware reads simultaneous samples without multiplexer skew.
100-LQFP — standard fine-pitch QFP for inspection
It is hand-solderable for prototypes, reflow-friendly for production, and the exposed leads make X-ray and AOI inspection straightforward.
