Frequently Asked Questions

What resolution and sampling rate does MCP3911A0-E/SS deliver in energy metering designs?

The MCP3911A0-E/SS provides 24-bit resolution across 2 channels at up to 125 ksps, enabling highly accurate current and voltage measurements needed for single-phase energy meters. Its integrated PGA allows signal amplification without external op-amps, reducing component count and board area.

How does MCP3911A0-E/SS interface with a host microcontroller in a data acquisition system?

The device communicates via a 4-wire SPI-compatible serial interface, operating at up to 20 MHz clock frequency. This makes it straightforward to connect to any microcontroller with an SPI peripheral, minimizing firmware complexity and supporting fast data transfers in industrial data acquisition systems.

What package and pin count should PCB designers plan for when using MCP3911A0-E/SS?

The MCP3911A0-E/SS is housed in a 20-pin SSOP package with a 0.65 mm pitch, offering a compact footprint suitable for space-constrained PCBs. The package body material is plastic/epoxy and it is RoHS compliant (JESD-609 code e3), supporting lead-free assembly processes.

When would MCP3911A0-E/SS be selected over a simpler 16-bit ADC for industrial sensing?

The MCP3911A0-E/SS is preferred when 16-bit resolution is insufficient and applications demand 24-bit dynamic range, such as in industrial weigh scales, precision current sensing, or power quality analyzers. Its 2-channel simultaneous sampling and on-chip phase compensation make it particularly suited for systems measuring phase angles between voltage and current signals.
