Power Management Integrated Circuits (PMICs) are key components in many electronic systems that are designed to ensure power delivery to support reliable operation. Voltage Reference integrated circuits (ICs), which are a type of PMIC, are an essential part of many electronic systems. The ADR02AUJZ-REEL7 is an example of a high-performance Voltage Reference IC, and it is specifically designed to ensure power efficiency and accuracy in modern electronic products. In this article, we will discuss the application fields of the ADR02AUJZ-REEL7, as well as the principle of its working.

Application Fields of the ADR02AUJZ-REEL7

The ADR02AUJZ-REEL7 is primarily used in high-performance automotive, industrial and consumer applications where accuracy, low power consumption, reliability and robustness are essential. This IC is designed for A/D (Analog-to-Digital) conversion, PLL (Phase-Locked Loop) reference voltage and oscillators, as well as for other applications in which the accurate production of a reference voltage is needed. In addition, the ADR02AUJZ-REEL7 can also be used to generate a robust, stable and low-noise voltage reference up to ±0.5%. This helps to ensure accurate and reliable operation of electronic systems that have stringent power management requirements.

The ADR02AUJZ-REEL7 has several features that make it suitable for use in many different types of applications. Its wide operating temperature range (-40°C to 125°C) allows it to be used in a wide range of conditions without compromising performance. Its 2KV ESD rating and its 2.7 V to 6.5 V voltage supply range make it suitable for high-voltage operation while minimizing power consumption. The IC is also isolated, with 8 mΩ ripple-rejection and 700 µA typical quiescent current. These features make it an attractive option for many design engineers who are looking for a reliable, low-power and accurate Voltage Reference IC.

Working Principle of the ADR02AUJZ-REEL7

The ADR02AUJZ-REEL7 Voltage Reference IC is based on a bandgap architecture and uses a differential pair of transistors as the feedback element. This differential pair of transistors has a high level of stability and accuracy, which is important for accurate reference voltage production. The differential pair of transistors is biased using a bias current source, which is adjustable to achieve the desired output voltage range. The output of the differential pair is then amplified by an op-amp before being fed back to the bias current source. This feedback loop allows the output voltage to remain stable and accurately as long as the environmental conditions remain the same.

The ADR02AUJZ-REEL7 also features an additional feature known as the Voltage Sense Circuit (VSC). The VSC is used to detect any variations in the output voltage due to load changes or other environmental conditions. The VSC can then be used to compensate for these variations and help maintain the accurate and dependable output voltage.

In summary, the ADR02AUJZ-REEL7 Voltage Reference IC is a high-performance IC that is suitable for a wide range of applications requiring reliable, low-power and accurate voltage reference. Its wide operating temperature range, ESD rating, voltage range and quiescent current make it an attractive option for many design engineers. Its bandgap architecture, differential pair feedback and VSC further makes it a reliable and accurate solution for many applications.
