This is a complete reference design for a multi-channel sensing solution for applications such as temperature controllers, data loggers, programmable logic controller (PLC) analog inputs, etc. 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.
- Complete combination of microcontroller (sensor analog front-end (AFE) and signal conditioning), buck regulator and isolation photocoupler with microcontroller (MCU) reference software
- MCU with AFE for sensing
- Reduces main MCU workload
- Flexible communication through 3-wire SPI interface
- Simple timing design for simultaneous multi-channel sensing
- Photocoupler isolation
- Long isolation distance
- No noise emission
