Evaluation and Demonstration Boards and Kits provide engineers and those studying electrical engineering with a condensed platform for experimentation and evaluation. EVAL-AD1937AZ is one such kit, which is capable of providing a diverse range of applications.

The EVAL-AD1937AZ is a complete hardware and software system designed to provide an evaluation platform and application development for the AD1937 stereo audio codec IC chip. There are numerous function blocks on the board that ultimately allow it to provide high performance audio performance evaluation. The EVAL-AD1937AZ provides the user with an system capable of multi-channel audio applications with microphone inputs. With its USB 2.0 interface, it is also a revolutionary system that offers the user advanced, multi-system audio streaming capabilities.

The EVAL-AD1937AZ is an evaluation board built around the AD1937 audio codec chip. It has on board components including: an audio codec, a USB 2.0 high speed interface, a microphone pre-amplifier, a power amplifier and a variety of other peripherals. The EVAL-AD1937AZ provides a complete audio performance evaluation system that is capable of four different I/O configurations.

The audio codec on board can achieve sample rates of up to 96khz and a programmable analog microphone pre-amplifier is also present that can be used for a variety of application. An independent power amplifier is available that can provide up to 25 watts of power.The stereo audio codec is designed for high performance audio performance and is integrated into the EVAL-AD1937AZ with an I2C bus, USB 2.0, a microphone pre-amplifier and numerous other peripherals. The programmable features of the board allow for the user to program the settings to best suit their application.

The system works by connecting to USB and the audio codec is just like any other USB audio device, recognizing the AD1937 codec by the USB port. The audio codec generates all the necessary audio signals that are required to process the input audio signal. A multiplexer is present which enables the user to switch between different audio signals and select the signal that best suits the application. The outputs of the multiplexer and the audio codec are then connected to the power amplifier and the microphone pre-amplifier, respectively. The power amplifier and the microphone pre-amplifier provide the necessary amplification of the audio signals. The outputs of the power amplifier and the microphone pre-amplifier are then connected to the desired outputs (speakers/headphones/etc.)

The provided software package allows for easy control and monitoring of the board. The board\'s USB connection allows for direct access to the audio codec and other peripherals. The software provides access to the different registers and settings that can be adjusted to best meet the user\'s needs. The input signal is then processed through the audio codec to generate an output signal. The outputs of the power amplifier and the microphone pre-amplifier are then connected to the desired outputs (speakers/headphones/etc.)

The EVAL-AD1937AZ is an ideal evaluation platform for testing and optimizing the AD1937 audio codec chip. With its four I/O configuration options, it is highly adaptable to different application scenarios. Its USB interface provides easy access to all board functions and its programmable audio codec settings make it an ideal solution for high performance audio evaluation.
