MCP3905L-E/SS General Description

Discover the MCP3905L-E/SS, an advanced energy measurement IC designed in compliance with the IEC 62053 international energy metering standard. Equipped with output features that provide a frequency proportional to the average active power at the inputs and a higher frequency output for instantaneous power measurement, this IC is essential for accurate meter calibration. Boasting two 16-bit delta-sigma ADCs with a programmable gain of up to 16, the MCP3905L facilitates the development of compact shunt meters capable of measuring a wide range of Ib and Imax currents. Its built-in on-chip voltage reference, characterized by ultra-low temperature drift of 15 ppm per degree C, ensures precision and stability across varying temperature environments. Additionally, the MCP3905L includes a fixed-function DSP for active power calculation and offers a reduced pulse width of the calibration output frequency, making it an efficient choice for low-power meter applications
