ADR431ARZ

The ADR431ARZ is an in-line voltage reference integrated circuit with diagnostic features. Its main purpose is to help maintain a specified level of voltage, with a wide input common-mode range, a low quiescent current and high settling time. The circuit provides diagnostic features such as over-voltage protection and current limiting.

In PMIC (Power Management Integrated Circuit) applications, the ADR431ARZ is commonly used as a voltage reference or voltage source, such as when optimizing power supply design. The device is able to accurately maintain its specified output voltage over a wide range of temperatures, making it ideal for low power, high frequency applications and for higher power supplies that require a low quiescent current, high accuracy voltage reference.

The ADR431ARZ includes two differential amplifiers and can be used to develop unique precision applications. The device operates at a wide range of temperatures and input voltages in order to provide the highest accuracy across a wide range of operating conditions. In addition, it is able to limit the total output current, with an adjustable current limit setting to provide an additional level of protection.

The ADR431ARZ is designed to be used as a voltage reference in any voltage regulated power supply. Its wide input common-mode range, low quiescent current and high settling time makes it an ideal choice for any comprehensive design. For those looking to create a system that can provide accurate voltage control, the ADR431ARZ can be used to provide a reliable voltage output over a wide temperature range.

The ADR431ARZ works by using an internal, matched differential amplifiers obtaining the voltage output from the internal reference source. From there, the output voltage is adjusted by the reference amplifier to achieve the required output voltage. The circuit includes two adjustable current limit settings for providing increased current protection, as well as two diagnostic features for indicating over voltage and over current faults.

The ADR431ARZ from ADI is a true technology breakthrough for voltage reference applications, providing an accurate and reliable voltage source over a wide range of temperatures and input voltages for those looking for a comprehensive design. Its low quiescent current, high accuracy and adjustable current limit settings provide the necessary protection and make it the ideal choice for any PMIC application.
