MCP3461-E/ST Frequently Asked Questions (FAQs)

  • Microchip provides a layout and routing guide in their application note AN1451, which recommends separating analog and digital signals, using a solid ground plane, and minimizing trace lengths and loops.
  • The MCP3461-E/ST has a built-in calibration feature. Refer to the datasheet section 4.4 'Calibration' for the calibration procedure. Additionally, Microchip provides an application note AN1349 that provides more detailed information on calibration and accuracy optimization.
  • The maximum sampling rate of the MCP3461-E/ST is 500 ksps (kilo-samples per second) in normal mode and 1 Msps (mega-samples per second) in turbo mode. However, the actual achievable sampling rate may be limited by the system's clock frequency, SPI communication speed, and other factors.
  • The MCP3461-E/ST outputs 24-bit unsigned binary data. The datasheet provides information on the output data format and scaling. Additionally, Microchip provides an application note AN1348 that explains how to handle the output data and perform scaling and offset corrections.
  • The datasheet provides information on the power-on reset and power-up sequencing requirements. In general, the VDD and VREF pins should be powered up simultaneously, and the CS pin should be held high during power-up. Refer to the datasheet section 4.1 'Power-On Reset' for more details.
