Analog to Digital Converters (ADCs) Evaluation Boards - ADS54J69EVM

The ADS54J69EVMEVM evaluation board from Texas Instruments is a compact yet comprehensive platform for rapid prototyping of applications involving Analog to Digital Converters (ADCs). This evaluation board is designed for use with TI\'s multi-channel, 16-bit ADC devices. Through its innovative pluggable module, this board enables engineers to quickly and easily prototype applications involving ultra-high-resolution analog-to-digital signal conversion.

Application Field

This powerful evaluation board is ideal for a wide range of applications. Space and medical electronics, for example, can benefit from its ultra-low power consumption and high sampling rate, while consumer electronics and telecommunications may take advantage of its small form factor and wide dynamic range. Additionally, the ADS54J69EVM’s integrated digital loop-back capability and its software-based user interface simplify design and significantly reduce the time it takes to get to a working prototype.

The board is also well suited to applications that require high speed signal conversion, such as radar or software-defined radios, as well as those employing acoustic sensing, ultrasound applications, linescan cameras, and more.

Working Principle

The ADS54J69EVM evaluation board consists of five elements – the main board, an analog-to-digital converter (ADC) chip, digital components, connectors, and the pluggable module. The main board contains the power supply and logic circuitry, as well as voltage regulators for the ADC. The ADC itself sits on the pluggable module and contains the necessary components (input buffers, analog-to-digital interface, etc.) for digital signal processing. Furthermore, two daughter boards outfit the pluggable module, providing signal conditioning and multiplexing capabilities.

When power is applied, first the power supply unit supplies the voltages needed by the converter\'s digital components. Then, the ADC chip and its attached components begin to process the analog signal between the input and output of the board. The converter generates a value, which is then processed by the digital components to generate an output value, which is sent to the output connectors to be received by the user.

The evaluation board provides extensive control within the system, through an intuitive graphical user interface designed to simplify the process of setting up, exploring, and testing multiple ADC configurations. This comprehensive GUI allows one to quickly configure many parameters that affect the operation of the board, and to monitor real-time operation of the board\'s various channels.

Conclusion

The ADS54J69EVM evaluation board is a versatile platform with powerful features for rapid prototyping of high-resolution analog-to-digital signal conversion. With its pluggable module, digital loop-back capability, and easy-to-use graphical user interface, it offers a comprehensive solution for leading-edge electronic applications in the consumer electronics, telecommunications, medical electronics, space, and many other markets.
