ADR03ARZ-REEL7 with its application field and working principle, can be categorized as PMIC – Voltage Reference.PMIC (Power Management IC) is a type of integrated circuit (IC) which is designed to provide the necessary power supply to other components or peripherals in a device. PMICs can be used to provide the appropriate power supply to each component in an electrical device. Depending on the level of integration, they can be divided into single-chip, two-chip and multi-chip solutions. PMICs also integrate many power management functions such as power supply sequencing and tracking, as well as environment and performance enhancements, into a single component or device.Among all PMICs, voltage references are used to provide a precise reference value which can be used for regulating the output voltage. Voltage references can be divided into different categories: band-gap voltage references, Zener diode references, temperature compensated Zener (TCZ) references, switched-capacitor voltage references, chopper-stabilized voltage references and dual channels voltage references. The ADR03ARZ-REEL7 belongs to dual channel voltage references. The working principle of dual channel voltage references is similar to regular voltage references, except that they have two different reference voltages instead of one. The device is usually used as voltage reference for signal conditioning applications, such as differential references, current mirror references and temperature sensors.The ADR03ARZ-REEL7 dual channel voltage reference is a high performance reference with low power consumption and a low voltage dropout of only 0.5V. It features a typical supply current of 1.2mA and a maximum operating temperature of 125°C. The device is a high accuracy, low noise reference and features an output voltage range of 0.2V to 6.3V.The ADR03ARZ-REEL7 can be used in a variety of applications including: low power USB, mobile telecommunications, high resolution analog-to-digital converters, mixed-signal systems, battery-powered devices, embedded applications, line receivers and many others.The ADR03ARZ-REEL7 has a high accuracy of 0.4% over temperature and a low temperature drift of less than 5ppm/°C. Additionally, the device features an integrated ESD protection of up to 4kV HBM and a low output noise of only 4nV/√Hz@1kHz. In conclusion, the ADR03ARZ-REEL7 is a versatile and reliable dual channel voltage reference that is suitable for a wide variety of applications. It is an ideal choice for any circuit requiring precision references of low power consumption and low voltage dropout. By exploiting the high accuracy and low noise of the ADR03ARZ-REEL7, users can achieve better resolution, higher dynamic range and more accurate measurements in their end designs.
