DAC9881EVM-PDK is a sample board of an Evaluation Kits used to control digital-to-analog converters. This board evaluates the features of TI’s DAC9881 precision converter. The main application field of the board is audio/power equipment, industrial process control, embedded systems and communications applications.

The DAC9881EVM-PDK includes an on-board adjustable voltage regulator for powering up the board from a wall outlet. The board also has an on-board 5V DC/DC regulator for powering up the analog circuitry. It includes two 12-bit differential voltage output DACs, one sample-rate 8-bit CT-ADC and two additional ADCs. The board can be used to control and adjust parameters of an audio system or to develop signals which can be used for measuring dynamic features of the audio system.

The board also includes a high-performance I/O system with a JTAG port for software loading, debug and evaluation. In addition the board includes an onboard USB port for connectivity between the board and a host PC. The DAC9881EVM-PDK is designed to be used in evaluating the capabilities of the DAC9881 device.

The board employs two separate power subsystems to power up the analog and digital signals. One of the power subsystems supplies power to the 9V DC IN terminal, which supplies power to the board for general operation. The other power subsystem is used to provide analog power to the board, and is supplied by the 5V DC IN terminal.

The board also features an internal reference voltage source to manage the offset voltages of the input signals and a digital signal processor to control the DAC9881 device parameter settings. The board uses a parallel input system to provide the user with a flexible and cost-effective way of evaluating the DAC9881 features and functions.

The DAC9881EVM-PDK includes a graphical user interface (GUI) for easy manipulation of the device settings. The GUI provides easy access to all of the device’s features and functions. It also allows the user to customize the audio output performance to suit their application. The board also features a high-performance analog and digital circuitry which enhances the performance and accuracy of the device.

The DAC9881EVM-PDK evaluation board is a powerful tool for evaluating the features of TI’s DAC9881 precision converter for audio applications. It has excellent analog and digital circuitry which enhances the performance and accuracy of the device.
