Voltage Reference is an important component in PMIC (Power Management Integrated Circuit), which inevitably influences the reliability and stability of the power system of PMIC. ADR02ARZ is a families of monolithic Voltage reference, which is developed from Analog Devices. This type of voltage reference has a variety of applications and working principle.

ADR02ARZ Application Field

ADR02ARZ can be used for low-side current-shunt monitoring and pressure-sensing applications. It includes an operational amplifier that can be used for precision current-source applications. It offers an improved temperature stability and accuracy throughout its operating temperature range, from -50 to +100 °C . Besides, it also can be used for wide-swing AC signal processing and voltage-controlled attenuation/gain control installation. The high-impedance of the output stage of the device is especially suitable for medical imaging and converting applications, as well as transimpedance amplifier, zero-drift amplifiers and voltage-controlled attenuators.

ADR02ARZ Working Principle

The principle of this type of voltage reference is that when a voltage is applied to the terminals of the device, the current present in the device will be proportional to the applied voltage based on Ohm’s law.This is then passed through the circuit to the reference voltage set point, thus stabilizing the reference voltage range. This device includes an operational amplifier, which amplifies the output signal and then provides a stable reference voltage. The device also contains a voltage regulator, which provides current control and also makes sure that the reference voltage is held steady.

The device integrates a precision resistor and capacitor, which improves the accuracy and linearity of the applied voltage readings. The device also provides protection against the over-voltage and over-current protection. The voltage reference product come with a wide variety of features, including low temperature drift, high resistance, low noise, and high accuracy. The device is also manufactured in various packages such as SOT23 and SOIC8.

In summary, ADR02ARZ is a families of monolithic Voltage reference, which has a variety of applications and working principle.
