NJM431E is classically categorized in the power management integrated circuit (PMIC), voltage reference product family. In this case, a voltage reference is a device capable of providing a stable, reliable reference voltage usually in the range of 1 to 6V, despite not depending on the load regulation. This makes NJM431E suitable for a large range of applications, specifically in power management but also involving measurement and audio/video.

NJM431E can be used for a wide variety of purposes, from power management to measurement and audio/video applications. As a power management device, this voltage reference operates by controlling the output voltage of the system to maintain a fixed voltage level. Specifically, it works as a feedback system, and depending on which version is used, it can be used as a shunt regulator, series regulator or a simple level shifter. NJM431E’s built-in soft start feature can minimize the in-rush current potentially reducing the large transient voltage spikes.

In measurement applications, NJM431E provides the stable reference voltage necessary for accurate, repeatable measurements and instrumentation. Due to its wide input range and its high accuracy, NJM431E can be used as an industry standard, delivering a reliable performance even in the presence of harsh environmental conditions. Additionally, the noise buffering effect of the voltage reference reduces the amount of electrical or radio frequency interference, resulting in improved signal integrity.

Another major application of NJM431E is audio/video control. It is able to provide the steady reference voltage for volume control as well as sound stage adjustments. It is also used for level shifting between different stages in a system, enabling a wide variety of audio/video applications. The proper reference voltage provided by NJM431E is essential for an effective headphone amplifier design, allowing improved sound quality and lower distortion.

NJM431E is a major innovation in the power management and audio/video control sector, providing reliable reference voltage and a wide variety of operational modes. The device is designed to be stable, low-noise and energy efficiency, being capable of providing the right voltage for a variety of applications, including power management, measurement and audio/video.
