• Voltage Reference-based Instrumentation

The LM185BXH-2.5 is also well suited for commercial, consumer, automotive, and industrial environments where high accuracy is required.

Working Principle

At the heart of the LM185BXH-2.5 is a CMOS-based temperature compensated bandgap reference. This bandgap reference operates as a virtual ground, and its output current is used to create a voltage reference for the device. This voltage reference is then isolated from the application circuit via a small reference voltage voltage regulator (which can be either a linear or switching type regulator). This isolation provides greater stability and accuracy when compared to a single-chip solution.

The LM185BXH-2.5 provides an accurate and consistent voltage reference over a wide temperature range (-40 to +125 °C). This makes it ideal for applications where temperature changes are common (such as battery-powered systems). Additionally, the device can withstand up to 6V of reverse voltage, making it suitable for many automotive applications.

One of the key features of the LM185BXH-2.5 is its ability to generate stable, precise voltage references despite line voltage fluctuations and environment changes. This feature makes the device a suitable choice for a wide variety of systems and applications. The LM185BXH-2.5 is also very low in weight and size, making it a convenient choice for server farms and other space-constrained systems.

Conclusion

The LM185BXH-2.5 is an integrated two-terminal PMIC (Power Management IC) voltage reference device that is suitable for many different applications. The device provides a stable and reliable voltage reference (2.5V) over a wide temperature range, and applications range from standard reference sources to bandgap references and calibration/testing applications. The device is also low in weight and size, making it suitable for space-constrained systems.
