  • 校准ADC内部偏移的光学微控制器DS4830

    Abstract: The DS4830 optical microcontroller's Analog-to-digital converter (ADC) offset can change with temperature and gainselection. However, the DS4830 allows users to measure the ADC internal offset. The measured ADC offset is added to the ADCoffset register to nullify the offset error. This application note demonstrates the DS4830's ADC internal offset calibration in theapplication program.

  • 精密DAC和看门狗提高模拟输出安全

    Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and data-acquisition systems. The Analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failure, optocoupler failure, or undervoltage condition occurs. A simple application is shown on how to implement thisfunction.
