Evaluation Boards - Analog to Digital Converters (ADCs) offer a diverse array of options to explore and take advantage of for different projects. The AD7768-V is one of these options and can help analog to digital conversion in a variety of applications. This article will explore the application field of the AD7768-V and the working principles behind its design.

The AD7768-V is a high-speed, low-latency ADC designed for use in embedded and portable designs. This device features a Zero-Drift JFET input stage, 12-bit signal resolution and 125MS/s throughput rate. It is also capable of sampling at low frequency operation and will improve signal robustness in noisy environments. This makes it ideal for use in medical equipment, automotive infotainment systems, and industrial environments.

The device’s power consumption is very low, allowing it to be integrated into a variety of applications. Additionally, its low differential nonlinearity (DNL) and integral linearity (INL) provide superior linearity and accuracy. The AD7768-V is compliant with the Automotive Electronics Council (AEC) qualification standard, making it a great choice for automotive applications.

The device also features several operating modes. In continuous operation mode (CMO), the device samples at a constant rate and can be used for real-time data capturing. The device can also operate in a "single-shot" mode (SSO) where it captures data with minimal latency. Finally, the device can be configured in a dual-channel "gated" mode (GMO) to save power and allow for multiple channels to be sampled simultaneously.

The working principle behind the AD7768-V is fairly simple. The device uses a JFET input stage to create a rail-to-rail input swing. This allows the device to accurately convert the analog signal into a 12-bit digital value. The device then uses successive comparison techniques to determine the digital output value. The output is then passed through a decimator to convert the analog signal into the desired format.

The AD7768-V is a highly versatile device that can be used for a wide variety of projects. Its low power consumption, high-speed operation, and superior linearity make it an excellent choice for applications where accuracy and speed are necessary. Additionally, its range of operating modes make it suitable for use in both real-time and low-power applications.
