The THS6042EVM is an Evaluation and Demonstration Board and Kit belonging to TI\'s data converter and signal chain solutions. It has wide application fields, including high speed communication, laptop audio, portable media players, gaming audio, medical systems, industrial audio, and automotive entertainment systems. Generally speaking, the THS6042EVM board can be used to power amplifiers and other signal chains and data converters.

The THS6042EVM evaluation and demonstration board is equipped with THS6042EVM functions. It supports either a differential or single-ended input. It can also automatically sense the digital input format and provide its output in either full-scale differential or single-ended output formats. Besides, this board and kit can provide a better design performance of a signal chain with energy efficient solutions. The THS 6042EVM board can optimize system power levels, reduce board component counts and simplify board development.

The THS6042EVM board is powered by a 5V power supply. The main work of the board is to convert digital audio data to analog signals. It uses an on-board 24-bit, 192kHz, Delta-Sigma DAC, the THS6018, to provide the convenience of digital audio, while the THS6042 can help to provide a higher quality analog audio signal. The THS6042 can also be used to control the input signal level, gain, and output level with its on-board PCM and analog control registers.

The THS6042EVM board includes two inputs. The on-board analog trimming controls can be used to adjust the input gain for accurate signal levels, and a band-select switch can be used to control the signal bandwidth. The THS6042EVM board also includes other inputs for digital and analog controls, providing flexible control of different modules. The board has a digital output, and the user can program the on-board ADC and DAC for various applications.

In addition, the THS6042EVM board includes a linear UART/SPI, and provides a workspace in order to achieve a digital interface connection between the board and host processor. The user can also use the on-board software tool to program the SPI for on-board DSP controls or for customizing the application. It is also convenient for users to monitor and regulate the board by using the on-board LEDs, potentiometers, and signal measurement points.

The working principle of the THS6042EVM board is simple. First, the analog audio signal is applied to the board’s inputs and the on-board 24 bit ADC will convert the signal into digital format. The digital audio data is then processed by a digital signal processor. Then, the processor will convert the digital data back into analog format. The output of the board is sent to the required speaker or power amplifier.

The THS6042EVM board is considered a one-stop solution for those who need to rapidly develop audio products. It provides a cost-effective evaluation and demonstration board and kit for designers to easily test various audio products. Furthermore, the board includes various inputs and outputs, allowing for an easy connection to required equipment.
