Renesas Electronics Sensor Signal Conditioner to Linearize Results
Renesas Electronics Sensor Signal Conditioner is a reference design to produce linear results from scale sensor elements. In scales, the sensor elements are non-linear; therefore, linearization needs to be done. In this solution, the workload is done in a sensor signal conditioner to allow close to 100% use of the Renesas Microcontroller (MCU) for customer applications.
Features
- No workload for the MCU, as the signal conditioner does all the pre-processing
- Tiny software footprint on the MCU side for precise scale functionality
- Offloading the MCU offers full MCU capability for user applications (e.g., Human Machine Interface (HMI), Tara function, etc.)
- The IO-Link PHY powers the entire application
- Easy adoption of a seven-segment LED via the GreenPAK™ family of cost-effective NVM programmable devices
- Reduced BOM, smaller PCB
Applications
- Industrial scales
- Point-of-Sale (POS) systems
- Retail scales
