Applications
The MCP3906A-I/SS is the analog front end for single-phase residential and light commercial energy meters, processing voltage and current signals from shunt or CT sensors on 2 channels. It is also used in power monitoring modules embedded in smart plugs, solar inverters, and EV charging stations where real-time watt-hour and VAR measurement is needed. Its SPI interface and SSOP-24 footprint make integration with PIC-based metering reference designs straightforward.

Frequently Asked Questions
How many ADC input channels does the MCP3906A-I/SS provide and what measurement parameters can they capture?
The MCP3906A-I/SS provides 2 analog input channels via sigma-delta ADCs, allowing simultaneous acquisition of current and voltage signals so the host MCU can compute active power in watts, reactive power in VAR, and cumulative energy in watt-hours.
What package does the MCP3906A-I/SS use and how does it affect PCB layout for an energy meter design?
The MCP3906A-I/SS comes in a 24-pin SSOP package, which has a 0.635 mm pitch and a compact body of approximately 8.2 mm × 5.3 mm, enabling a dense PCB layout alongside the metering MCU and minimizing the analog signal path length from the sensors.
Which host interface does the MCP3906A-I/SS use and what microcontroller families is it compatible with?
The MCP3906A-I/SS communicates over an SPI-compatible 4-wire serial interface running at up to several MHz, making it directly compatible with Microchip PIC16, PIC18, and dsPIC33 microcontrollers as well as other MCUs with hardware SPI peripherals.
Is the MCP3906A-I/SS RoHS-compliant and what lead-free coding applies to this part?
Yes, the MCP3906A-I/SS carries JESD-609 code e3, confirming it is a fully RoHS-compliant, Pb-free device with a peak reflow temperature of 260°C, meeting IPC/JEDEC J-STD-020 requirements for lead-free assembly processes.
