What the seven 24-bit sigma-delta ADCs mean for your BOM
Its standout feature is the integrated set of seven 24-bit sigma-delta ADCs, purpose-built for polyphase energy metering and multi-channel precision measurement. This eliminates the need for external analog front-ends in designs that must digitize multiple voltage and current channels simultaneously — a BOM simplification that directly reduces board area and component count in smart meters, power-quality monitors, and industrial data loggers. The 62 general-purpose I/O lines and connectivity set — I²C, IrDA, LINbus, SPI, UART/USART — give the part enough interface bandwidth to talk to a host processor, an external display, or a wireless module without multiplexing.
Industrial temperature and package fit
The 100-pin LQFP package with a 14x14 mm body is a surface-mount footprint that routes easily on a two-layer board, though the high I/O count (62) may push a dense design to four layers for signal integrity.
