Isolated Multi-Channel Sensing Solution

Renesas’ multi-channel sensing solution reference design eliminates noise interference and works to keep ADC results accurate

Image of Renesas’ Winning Combination - Isolated Multi-Channel Sensing SolutionRenesas’ winning combination reference design for isolated multi-channel sensing solutions for applications such as temperature controllers, data loggers, programmable logic controller (PLC) analog inputs, and more. Isolation between digital and analog components (and among channels) eliminates the noise interference and works to keep the analog-to-digital converter (ADC) results accurate.

Features
  • Combination of a microcontroller sensor [analog front-end (AFE) and signal conditioning], buck regulator, and isolation photocoupler with microcontroller (MCU], reference software
  • Photocoupler isolation
    • Long isolation distance
    • No noise emission
  • MCU with AFE for sensing
    • Reduces main MCU workload
    • Flexible communication through a three-wire serial peripheral interface (SPI)
    • Simple timing design for simultaneous multi-channel sensing
