Analog to Digital Converters (ADC) are defined as electronic devices that transform analog signals, such as temperature, light, voltage, or pressure signals, into digital ones. This hardware technology is widely applied in various industries, ranging from healthcare to automotive industry. Among many ADC models currently available on the market, one of the more frequently used is the AD7766BRUZ. This article aims to introduce its application field and working principle.

Application Field of AD7766BRUZ

The AD7766BRUZ is a wired device, belonging to the first-generation charge-redistribution (CR) technology group. It has 16 input pins for external connections, and its signal inputs can range from four different sources, such as voltage, strain, current, or temperature. Meanwhile, four connectors on the top of the device enable four interconnects to the various signal sources. The major feature of this converter is its embedded voltage reference, which is much smaller than traditional voltage regulators and used to provide reference voltage.

Thanks to its multiple applications, the AD7766BRUZ is highly recommended by many manufacturers. In particular, its accuracy and stability are improved even when it is used in harsh industrial environments or noise-prone applications. In particular, its 16-bit resolution makes it suitable for precision measuring and signal processing. For this reason, it is popularly applied in industrial fields such as machine maintenance, assembly line monitoring, ultrasound imaging, and medical signal recording. Furthermore, the device’s ability to eliminate signal integrity errors proves its capability of being used in automotive industry, especially in vehicle motion control, sensors, and main driving control.

Working Principle

The AD7766BRUZ is a type of integrated circuit (IC). As a core component of the converter, it effectively processes analog signals received from input pins by connecting these pins to an internal analog signal conditioning circuit. This internal circuit features an analog-to-digital (A/D) converter, known as the Delta-sigma converter, which is the most vital part of the AD7766BRUZ. This A/D converter is set in a pipeline structure, with the settled signal output of each stage passed to the A/D converter of the next stage. It is the combination of each step’s A/D conversion that creates the 16-bit output represented by digital values.

In addition to the internal pipeline setup, the AD7766BRUZ also features an integrated ADC and Voltage Reference. The ADC itself is responsible for the operational specific characteristics, while the reference voltage is applied to different pins for measuring analog inputs. Subsequently, the resulting digital values are then transferred and stored in an internal memory that serves as an output for the device.

To conclude, the AD7766BRUZ is a very popular analog to digital converter thanks to its various applications and highly accurate conversion. Its integrated A/D converter, Delta-sigma converter, voltage reference, and internal memory enable precision measuring and signal processing in the most efficent way. Moreover, its small size and low power consumption makes it suitable for extensive industrial applications and flexible integration.
