ADCs, or analog-to-digital converters, have become invaluable in modern technology. With a vast range of applications from speech recognition to embedded systems, they are an integral part of any electronic system. The ADS8860EVM-PDK analog-to-digital converter evaluation module (EVM) is a comprehensive platform for quickly evaluating the ADS8860 analog-to-digital converter from Texas Instruments. This application note provides an overview of the popular applications for the ADS8860EVM-PDK as well as the working principles behind its use.

Application Field

The ADS8860EVM-PDK is a highly advanced ADC evaluation module (EVM) that is designed to maximize the performance and capabilities of the ADS8860 converter. This EVM is ideal for applications that demand high resolution and ultra-low power consumption, including, for example, medical imaging, streaming audio and video, and precision measurement.

The ADS8860EVM-PDK is a comprehensive platform that provides the user with a range of powerful features and advanced design capabilities, including an easy to use graphical user interface (GUI). This EVM contains all the necessary components for quickly setting up and evaluating the ADS8860 ADC, including an Input Signal Connector Board, a Voltage Reference Connector Board, a voltage supply regulator, a power supply, and associated software components.

The ADS8860EVM-PDK supports multiple input configurations, including unipolar and bipolar analog input, digital I/Os, and selectable input ranges. The EVM also provides diagnostic features including Single-Shot and Logarithmic Acquisition, allowing users to quickly evaluate the performance of their ADC design. Additionally, the EVM provides built-in self-calibration and self-test capability for comprehensive evaluation.

Working Principle

The ADS8860EVM-PDK uses a standard architecture for its evaluation. This architecture is based on the I2C bus to control all functions of the ADC and to read data. The I2C bus is used to communicate with a PC or other host controller, allowing for remote control of the EVM. The EVM can be used with both single ended and differential input signals. Differential input signals are provided by the two input terminal connectors: Vin+ and Vin-. The Vin+ and Vin- terminals are also used to provide the reference voltage VREF.

The ADS8860 EVM also features an enable pin that is used to activate the EVM. When the enable pin is active, the EVM starts the internal clock and then begins the evaluation process. The internal clock enables the ADC to sample the analog input signal at very precise intervals. The ADC then converts the analog input into a digital representation and sends the data to the host controller via the I2C bus.

Finally, the ADS8860EVM-PDK supports a variety of output formats, including serial (SPI), serial (I2C), and parallel. These different outputs provide the user with flexibility in terms of data transmission and the ability to choose the most suitable output format for their particular application.

The ADS8860EVM-PDK is a comprehensive evaluation tool that supports a wide range of ADC applications. Thanks to its easy-to-use GUI and advanced features, users can quickly and accurately evaluate their ADC design. By adding the ADS8860EVM-PDK to your designs, you can take advantage of all of its features to ensure the highest possible performance.
