Microchip Technology Inc., Chandler, AZ, offers the MCP3909 energy-measurement IC and reference design that lets you develop and bring meter designs to market quickly. The MCP3909 has two 16-bit delta sigma ADCs that can be accessed through its SPI interface while simultaneously providing a pulse output with a frequency proportional to the active-power calculation. Typical measurement error is 0.1% over a 1000:1 dynamic range and draws 4 mA. The 3-phase energy meter reference design includes 3 MCP3909 ICs, a PIC18F2520 that performs the power calculations, a PIC18F4550 microcontroller that provides a USB interface, and software.
