Introduction:Evaluation boards are widely used for evaluating an example of any specific electronic component or system. This includes microcontrollers, memory components, analog-to-digital converters (ADCs), digital signal processors (DSPs), and much more. The EVAL-AD7923CBZ evaluation board is designed for capturing and analyzing the sign-magnitude data output from the AD7923 (13 bit) analog-to-digital converter IC. The EVAL-AD7923CBZ board is a complete, self-contained evaluation solution complete with all the necessary components and cables to enable an AD7923 evaluation.The Main Functions of EVAL-AD7923CBZ: The EVAL-AD7923CBZ evaluation board has four main functions. Firstly, it provides a ±2.2 V analog input reference as well as the analog input range and full-scale voltage range of the AD7923. Secondly, it provides an analog multiplexer with 32 single-ended analog inputs with a full-scale voltage up of ±2.2 V. Thirdly, it provides digital control of the analog input reference as well as the MUX (multiplexer) selection. The last function is to provide power supplies and digital outputs from the digital logic used in the AD7923. EVAL-AD7923CBZ Application Field:The EVAL-AD7923CBZ evaluation board has various applications and can be used in many different fields. It is widely used in medical monitoring systems, industrial process control systems, and automatic test equipment. It can also be used to measure pressure, temperature, position, and velocity. Additionally, the board is small and versatile, thus making it suitable for many portable applications such as portable medical devices and handheld instrumentation.EVAL-AD7923CBZ Working Principle:The EVAL-AD7923CBZ evaluation board works based on the AD7923 analog-to-digital converter. The AD7923 analog-to-digital converter is a 13-bit resolution delta-sigma converter. It has an integrated low noise amplifier, multiplexer, and programmable gain amplifier. The analog signal is first conditioned by the low noise amplifier, multiplexer, and programmable gain amplifier before it is applied to the voltage-controlled oscillator. The output of the VCO is an analog 1-bit signal which is passed through a digital filter . Then, the digital signal is decimated and converted to digital data via the ADC\'s internal 13-bit SAR converter. Finally, the digital data is provided to the user either through a serial bus or through the parallel data outputs.Conclusion:The EVAL-AD7923CBZ evaluation board provides a complete, self-contained evaluation solution to enable development of the AD7923 analog-to-digital converter. This system offers four main functions: providing an analog input reference, providing an analog multiplexer, providing digital control of the analog input reference, and providing power supplies and digital outputs. The board has various applications and can be used in many different fields such as medical monitoring systems, industrial process control systems, and automatic test equipment. The board works based on the AD7923 analog-to-digital converter, which is a 13-bit resolution delta-sigma converter. All these features make this board a very powerful evaluation tool for analog-to-digital conversions.
