Introduction:
The ADR520ARTZ-REEL7 is a Voltage Reference Product manufactured by Analog Devices, which belongs to the PMIC (Power Management IC) family. The product is a reliable reference voltage source and is ideal for a variety of applications, including as a support device for low power and portable applications. The device is also capable of efficiently providing a stable and reliable output voltage over a wide range of temperatures and operating conditions. In this article, we will discuss the application field and working principle of the ADR520ARTZ-REEL7.Application Field:
The ADR 520ARTZ-REEL7 is a precision voltage reference with a single +2.5 V output voltage. The device is most commonly used in power supply and battery management applications. It is well-suited for powering precision applications such as data converters, RF circuitry and temperature measurement. Additionally, the device is sometimes used in communication and networking applications, where its versatility as both a reference and a power regulator comes in handy.Working Principle:
The ADR520ARTZ-REEL7 works on the principle of negative feedback control, which helps to maintain a precise output voltage in spite of a fluctuating input voltage. The device supports a wide input voltage range, from 5.5V to 16V, with low output voltage variations of only 0.04%. Additionally, it offers an operational temperature range of -25°C to 85°C, and comes with some advanced features such as protection against reverse voltage, under voltage lockout, logic-controlled output and precision on/off control.The main components of the device includes a band-gap reference, a low-power operational amplifier and a current mirror. The band-gap reference produces a fixed voltage of 1.26V, which can be used as a reference for precise measurements. The operational amplifier amplifies the difference between the reference voltage and the measured current. Consequently, the output voltage from the device is precisely regulated and constant. Meanwhile, the current mirror helps to reduce its power consumption and improves the stability of the outputted voltage.Conclusion:
In conclusion, the ADR520ARTZ-REEL7 is a reliable voltage reference device from the PMIC (Power Management IC) family. The device is commonly used in power supply and battery management applications, and offers a wide operational temperature range with a precise output voltage. It works on the principle of negative feedback control, which helps maintain a constant output voltage in spite of a fluctuating input voltage. The device also includes some advanced features such as reverse voltage protection and logic-controlled output.
