Evaluation and Demonstration Boards and Kits are a vital part of researching and enhancing the development of new products. Among those boards is the PGA300EVM- 034, what can be found in its application and working principle will be discussed in detail in the following sections.

The Application of PGA300EVM-034

The board of PGA300EVM-034 is intended for those engineers who are working on audio circuit design. this board is able to provide you the very basics of tools and components you need for the design, and the complexity of this board ranges from the simplest S/H and non-inverting amplifier configurations, to the complex system like power amplifier for speaker and monitor.

What’s more, the PGA300 is provided as an very user-friendly platform. This platform allows the engineers to connect easily to the outside world, contains headers for utilizing National Instruments (NI) LabVIEW software, as well as for those users who prefer to use more classic way to measure, a set of resistors, capacitors and sockets for measuring purpose is also added into the kit.

Finally, thanks to its user-friendly feature, the PGA300EVM-034 also provides you the most convenient way possible for contractors to develop their own device. they can use this board as their premade platform, customize their own device on the top of it, and checks if everything is running properly with those resources inside the packages.

The Working Principle of PGA300EVM-034

The working principle behind the PGA300EVM-034 is quite simple, and the main component of the board is the Analog Devices PGA300 Signal Processing Device. It takes the most control of the signal processing and control of the board. At the same time, the board is also able to provide users to CPU interface as well. That is:

The CPU interface enables the engineers to execute commands in the task as a sequence and the PGA300 device will be programmed accordingly. For instance, the PGA300 can adjust the input voltage and the output voltage level as well as providing different signal processing tasks. The PGA300 also changes the input and output rates as well as the order in which data is sent and received.

The second component of the board is the I/Q Sensor, which is used to measure and monitor the sound level or frequency. The monitoring system is able to send high or low frequency signals to the PGA300 so that it could react accordingly.

Conclusion

In conclusion, the PGA300EVM-034 is an unique piece of board which provides the very basics of audio signal processing. It is very convenient for users to develop their own device with the resources that are provided to them. Its CPU interface is designed to run tasks in a sequence and the I/Q Sensor helps to monitor and measure the sound frequency.
