Analog-to-digital converters (ADCs) bridge the gap between analog signals and digital designs, allowing a smooth conversion between the two domains with minimal noise or distortion. The ADS7866EVM is an evaluation board that makes it easy to assess the performance of Texas Instruments’ ADC-integrated devices in real-world settings. In this article, we will take a closer look at the application field and working principle of the ADS7866EVM.

Applications of the ADS7866EVM

The ADS7866EVM is an ideal device for evaluating Texas Instruments’ 16-bit, 1-channel and 8-channel ADC-integrated devices. With its single-supply design, the ADS7866EVM minimizes noise and power consumption while maximizing performance. The board can be used to evaluate the performance of TI’s ADC devices in analog-to-digital conversion and signal conditioning applications. It is ideal for sensing, medical, industrial, and consumer applications that require high-precision conversions.

ADS7866EVM Working Principle

The ADS7866EVM consists of a 16-bit ADC core, analog buffers, and a temperature sensor that is interfaced with onboard ADC. The temperature sensor has two input pins; one for the reference voltage (analog input) and one for the ADC output voltage (the digital output). The onboard ADC converts the reference voltage into a digital code, which is then sent to the temperature sensor to get a precise temperature measurement. The temperature measurement can then be used to adjust the gain of the analog buffers for maximum accuracy.

The ADC core on the ADS7866EVM allows for up to 8-channel simultaneous analog-to-digital conversion. Each user-defined channel can be programmed with a different analog input range, sampling rate, and output resolution. The board also includes an onboard signal conditioning system that performs signal conditioning tasks such as noise filtering, signal scaling, offset, and gain adjustment. This allows the board to accurately convert analog signals with minimal noise and distortion.

In addition, the ADS7866EVM includes onboard EEPROM memory for storing calibration values, allowing the board to maintain calibration accuracy throughout its life. With its user-friendly graphical user interface (GUI), users can easily program and configure the ADS7866EVM. Once programmed, the board can be used for evaluating the performance of TI’s ADC devices in real-world settings.
