Analog-to-Digital Converters (ADCs) play a vital role in the world of digital technology and their applications are tremendously varied. One of the most common types of ADC is the ADS8688AEVM-PDK, which is a high precision low noise ADC with integrated power management. The board can be used for data acquisition, digital audio, Home Audio, etc. Let’s take a look at the application field and working principle of this ADC board.

The Application Field of ADS8688AEVM-PDK

The ADS8688AEVM-PDK is an all-in-one multi-channel ADC evaluation board designed to evaluate the performance and features of Texas Instruments’ ADS8688 low noise and high precision 4th generation Delta-Sigma Converters. The board can work with 10-bit, 12-bit and 16-bit resolution ADCs and with different sample rate. It is primarily intended for the consumer audio applications, as it is flexible enough to be used in a wide range of audio applications.

For example, it can be used in an audio entry system for recording data from microphones. It can also be used for Voice-over-IP applications, audio broadcasting, etc. In addition, it can be applied in medical applications such as ultrasound imaging, ECG recording or EEG recording.

Besides that, the board can also be used in automotive applications such as electronic control unit, radio frequency identification or automotive infotainment systems and also security systems such as surveillance and access control.

The Working Principle of ADS8688AEVM-PDK

The working principle of the ADS8688AEVM-PDK is based on sigma delta conversion. Sigma delta conversion is a form of modulation principle in which an analog signal is converted into a digital signal using a combination of sigma delta modulation and digital noise shaping.

The analog signal is modulated with the help of a feedback loop. The modulated signal, referred to as a delta-sigma signal, is then filtered to remove any noise and it is then converted into a digital value. This digital value represents the value of the original analog signal and it is then stored in the memory of the device.

The ADS8688AEVM-PDK board is equipped with a high sampling rate for better noise-free performance and efficient data transfer. It also includes a low power mode which helps to reduce power consumption.

Conclusion

In conclusion, the ADS8688AEVM-PDK evaluation board is an advanced high precision low noise ADC board which can be used for a wide range of audio applications such as Voice-over-IP, medical applications, automotive applications and security systems. It works on the principle of sigma delta conversion and it is designed to provide high sampling rate and low power consumption.
