Features:

EVAL-AD7767-1EDZ is ideal for use in a wide range of applications. It has many useful features, including:

• Low power consumption
• High accuracy and resolution (16-bit)
• 16-bit SAR and 14-bit differential input
• Low drift over frequency and temperature
• Excellent signal-to-noise ratio
• High common-mode rejection ratio (CMRR)
• Low profile and small form factor
• Low power shutdown mode
• Extension boards available for analog and digital I/O

Working Principle:

The EVAL-AD7767-1EDZ ADC is based on a successive-approximation-register (SAR) architecture. It samples an input signal at a fixed sampling frequency, and then converts it into a digital output code which is proportional to the input voltage. The board uses on-board precision references to ensure that the output is accurately converted. The board is also designed to work with a wide range of external references, allowing flexibility in the environment in which the board is used.

The board features an extended temperature range from -40°C to +105°C and can operate up to 140°C. It also has a high common-mode rejection ratio (CMRR) of >90 dB, ensuring good accuracy and performance. The board also features a power saving shutdown mode where the power consumption can drop to as low as 3mW.

The board also has extension boards available for added versatility. These boards can be used to connect to external devices or to interface with digital I/O. The extension boards also feature signal conditioning and buffering to improve the signal quality coming from external sources.

Overall the EVAL-AD7767-1EDZ is a powerful yet flexible solution for a wide range of applications. It is capable of both low power and high precision operation with easy of use and configuration making it an ideal solution for many applications.
