Applications
The MCP3901A0T-I/SS targets single-phase and polyphase energy meters requiring simultaneous sampling of current and voltage channels with high dynamic range. Its dual-channel architecture suits smart meter designs where two 24-bit ADC inputs feed an MCU for active and reactive power calculation. It is also applied in power quality monitors and industrial data acquisition front-ends where a low-noise SPI-interfaced AFE simplifies system design.

Frequently Asked Questions
How many ADC channels does the MCP3901A0T-I/SS provide and what interface does it use?
The MCP3901A0T-I/SS provides 2 simultaneous-sampling ADC channels with an SPI serial interface, enabling a metering MCU to read both current and voltage channels concurrently for accurate power calculations in single-phase energy meters.
Which package does MCP3901A0T-I/SS come in and how does that affect PCB layout for energy meters?
It uses a 20-pin SSOP package with a narrow body that fits tightly on a compact energy meter PCB, keeping analog front-end traces short and reducing noise pickup compared to larger DIP or wide SOIC alternatives.
When should a designer choose MCP3901A0T over a single-channel AFE for a metering application?
Any design measuring both line current and voltage simultaneously—such as a residential kWh meter or a 3-phase power monitor—benefits from the MCP3901A0T's 2 channels, eliminating the cost and skew of two separate single-channel ADC devices on a 5V or 3.3V supply rail.
Does MCP3901A0T-I/SS comply with RoHS regulations for lead-free assembly?
Yes, the MCP3901A0T-I/SS carries a lead-free Pb-free code and JESD-609 e3 rating, confirming RoHS compliance for assembly with standard Sn-Ag-Cu solder pastes in automated SMT lines at reflow temperatures up to 260°C.
