Working principle

BU9437AKV-E2 mainly consists of an analog-to-digital converter and a digital-to-analog converter, two crucial components for signal conversion. The analog-to-digital converter (ADC) is designed to convert analog input voltages into digital output signals, while the digital-to-analog converter (DAC) enables the conversion of digital data into analog output signals.The input of the ADC is connected to an analog signal source, such as a sensor or a voltage source. When the input voltage is stable, the ADC measures the analog signal and converts it into a digital output. This process is performed by comparing the input voltage with a reference voltage. The reference voltage is used to define the dynamic range of the input voltage and to provide an accurate conversion resolution which ensures that the output digital signals are as precise as possible.The digital output of the ADC is then connected to the input of the DAC. The DAC converts the input digital signals into analog output signals. This process is performed by using a method called the ‘Flash algorithm’. In this method, a series of voltage references stored in a memory are compared with the input digital data to generate a corresponding analog output voltage.The DAC output is then fed back to the system, either applying it to an actuator for its operation or measuring it for further processing. This process is repeated in a loop to ensure precise and accurate signal conversion.

Conclusion

BU9437AKV-E2 is an energy-efficient, low-cost, and small-size interface device with a wide range of applications across the fields of industrial control, medical diagnostics, audio/video, home automation, and power conversion.
