PMIC, or power management IC, are integrated circuits used to manage a system\'s power supply. One type of PMIC is the voltage reference, which helps maintain a constant voltage level. The AD780BN is one such voltage reference utilized in various systems. This article will explore the AD780BN\'s application fields and working principle.
Application Fields
The AD780BN is a monolithic voltage reference featuring low temperature drift, low power consumption, and a low output voltage noise. Its applications span multiple fields such as medical, automotive, communications, industrial, and consumer markets. The medical sector utilizes the AD780BN for its consistent voltage output, low zero-drift accuracy and high ESD protection, making them ideal for high-accuracy low-impedance measurements.Automotive applications often require strict standards and high-reliability operation. The AD780BN meets both of these requirements, which makes it well suited for automotive systems.The AD780BN also performs well in communications systems. Its low output voltage noise and low power consumption allow it to contribute to communication system stability and accuracy.In the industrial sector, the AD780BN plays an important role in a wide range of systems, such as microprocessor-controlled products, factory automation systems, consumer electronic equipment, and other electrical and electronic products with rigorous temperature requirements.Lastly, consumer markets benefit from the AD780BN’s consistent voltage and low power consumption. These features allow consumer electronics to operate with consistent power, ensuring reliable performance and product life.Working Principle
The AD780BN is a precise voltage-reference IC consisting of an improved temperature-compensated bandgap, a regulated current source and a voltage divider. It can generate precise constant-voltage references from a single-supply rail, such as a 5V rail.The AD780BN works by firstly using bandgap reference technology to generate a dedicated precise, low-temperature coefficient voltage reference. The bandgap reference (also known as a bandgap circuit) is a temperature-stable amplifier circuit that generates a voltage even in the presence of temperature fluctuations. Next, the regulated current source amplifies the bandgap’s output voltage, allowing the voltage divider to accurately adjust the output voltage to the desired level.Finally, the voltage output pin of the AD780BN outputs the regulated reference voltage, precisely adjusted to the desired level. The AD780BN is able to maintain this voltages level even in changing temperatures or power supply levels.Conclusion
The AD780BN is a powerful and reliable voltage reference IC, utilized in many applications from medical to consumer. Its low power consumption, low temperature drift, and low output voltage noise make it ideal for high precision and low impedance measurements. The AD780BN generatesthe reference voltage via bandgap reference technology, regulated current source and a voltage divider. It is well suited for applications that require precise power management and consistent voltage.The specific data is subject to PDF, and the above content is for reference
