Six-channel AFE targets 3-Phase measurement
Additional integrated features include programmable gain amplifiers (PGAs), a low-drift voltage reference and phase-delay compensation, for a reduced external component count that increases design flexibility and lowers costs.
The MCP3903 AFE targets the utility and industrial markets, such as utility meters, power-monitoring devices and instrumentation devices. Government regulations and trends in smart metering, along with the Advanced Metering Infrastructure, have dramatically increased the need for products that offer precise measurements in multi-phase metering, while simplifying designs and reducing costs.
The MCP3903 claims to deliver this functionality by providing a highly accurate solution with integrated features that enable design flexibility. The MCP3903’s six 16-/24-bit Delta-Sigma ADCs enable the simultaneous sampling of six inputs, making it suitable for three-phase power monitoring and metering.
