24-bit precision for energy and power monitoring
The MCP3901A0T-I/SS is a 24-bit analog front end (AFE) from Microchip, integrating two independent conversion channels in a 20-SSOP package. It is designed for energy metering and precision data acquisition where simultaneous sampling of voltage and current is required.
Two-channel simultaneous sampling
The two-channel architecture allows the AFE to digitize voltage and current waveforms at the same instant, preserving phase information critical for accurate active and reactive power calculations in polyphase meters. Each channel delivers true 24-bit resolution, providing the dynamic range needed to measure small signals in the presence of large line-frequency components without external gain stages.
