A voltage reference, sometimes referred to as a voltage regulator, is an electronic device that produces a stable voltage for a variety of applications such as powering electronic components, controlling power in electronic circuits, and providing reference levels for instrumentation. There are many types of voltage references available on the market, from simple discrete components to more sophisticated integrated circuits. The AD586LRZ-REEL is one such integrated circuit that has been specifically designed to provide precise and stable voltage references in a variety of applications. In this article, we will discuss the application fields and working principle of the AD586LRZ-REEL.

Application Fields

The AD586LRZ-REEL is a precision voltage reference designed to support a wide range of applications. It is commonly used in digital-to-analog converters, portable audio products, computer systems, automotive systems, and instrumentation. The device is designed to provide a stable voltage output of up to 2.5V and a low power consumption of 10mA for low battery applications. Furthermore, its low output noise and low temperature drift of 0.0005V/°C make it ideal for precision applications.

Working Principle

The AD586LRZ-REEL is an integrated circuit (IC) that uses a bandgap circuit to produce a voltage reference. A bandgap circuit is essentially a circuit composed of transistors, voltage sources, resistors, and capacitors that is capable of providing very precise and stable voltages over a wide temperature range. In the case of the AD586LRZ-REEL, it uses a proprietary bandgap circuit architecture, called the PIBOS (Precision Integrated Bandgap reference on Silcon) that eliminates the need for a temperature sensor and provides a very precise voltage reference of 2.5V. The output voltage of the device is internally trimmed to less than 0.2% accuracy, so no external calibration is required.

The device is also equipped with short-circuit and thermal shutdown features to protect itself from current and temperature overloads, respectively. The short-circuit and thermal shutdown features can be programmed with the externally accessible trim pin.

Conclusion

The AD586LRZ-REEL is a precision voltage reference that has been specifically designed to provide precise and stable voltage references in a variety of applications. Its low output noise and low temperature drift make it ideal for precision applications, while its low power consumption makes it suitable for low battery applications. The device is equipped with short-circuit and thermal shutdown features to protect itself from current and temperature overloads. Therefore, it is a great solution for a wide range of applications.
