AD7920BKSZ-500RL7 Application Field and Working PrincipleData Acquisition - Analog to Digital Converters (ADC) involve the conversion of analog signals into digital form in order to be usable by digital systems such as computers. The main application of such devices is in measuring physical properties such as temperature, pressure or sound level. A typical ADC has a number of analogue input ports that are connected to transducers, which measure the physical properties. The transducers produce an electrical signal resulting from the physical properties, which is then converted into a digital signal for use by the system.The AD7920BKSZ-500RL7 is a low power, high performance 8-bit ADC which is suited for medical, automotive, instrumentation and consumer applications. The device uses a sigma-delta modulator architecture, which helps it achieve a low power consumption of only 500mW. The AD7920BKSZ-500RL7 features an internal reference, allowing for easy integration into a range of applications, and also features on-chip monitoring and housekeeping functions.In order to understand the working principle of the AD7920BKSZ-500RL7, it is necessary to first understand the basics of a sigma-delta modulator. This type of modulator can be used to convert an analogue signal to digital form, and is based on oversampling the signal followed by digital filtering. The basic principle involves the conversion of an input signal into a sequence of digital data with a resolution that can be much higher than the input resolution. The main advantage of this type of architecture is that it can reduce the amount of electrical power consumed when compared to other types of ADCs. The AD7920BKSZ-500RL7 is a continuous-time fractional-N modulator which uses the sigma-delta modulator architecture. It uses an internal bandgap reference to achieve an accuracy of up to 8 bits, with input signals ranging from -2.4V to +2.4V. The device has an on-chip oscillator, allowing for easy integration into a system.The AD7920BKSZ-500RL7 also features a self-calibration block, which allows for the device to adjust itself to give maximum accuracy at temperatures outside of the specified range. This feature can help improve system performance in hostile environments such as those encountered in automotive applications.The AD7920BKSZ-500RL7 is ideally suited for applications such as medical, automotive, instrumentation and consumer applications. The device is also suitable for applications requiring low power consumption and low cost, due to its high performance and low power consumption.The AD7920BKSZ-500RL7 is a sigma-delta modulator which consumes only 500mW of power and is capable of achieving 8-bit accuracy. The device is ideally suited for applications including medical, automotive, instrumentation and consumer applications, and features a self-calibration block for improved accuracy at temperatures outside of the specified range. The AD7920BKSZ-500RL7 is a low cost, low power and high performance device, making it an ideal choice for a range of applications.
