The LM4040BIZ-2.5 is a precision 2.4995 V micropower voltage reference and temperature sensor. It is a component of the PMIC – Voltage Reference family. It is used to provide a precise voltage reference and a control signal to the measuring or output circuit. It is self powered, reducing system component cost and board area.

The primary application of the LM4040BIZ-2.5 is as a low power, micropower voltage reference. It has a wide operating temperature range, from -55°C to +125°C, and can be used in a wide range of environmental conditions. With a low quiescent current of 1µA, the LM4040BIZ-2.5 can be used in battery-powered applications.

The working principle of the LM4040BIZ-2.5 is based on the zener diode principle. It consists of a series of p-n junctions arranged in such a way that, when the voltage across the reference junction is greater than the Zener breakdown voltage, the current through the device will flow in the reverse direction, causing a reverse bias across the junction and thereby reducing the current. The reference voltage (2.4995V) is controlled by the Zener diode, and any change in the forward voltage applied to the junction will cause a corresponding change in the reference voltage.

The LM4040BIZ-2.5 is designed to provide high accuracy and low noise operation in both commercial and automotive temperature ranges. The tight initial tolerance of the reference voltage, combined with its low temperature coefficient, makes the device an ideal choice for precision voltage references. Its low quiescent current consumption, combined with its low input capacitance and output resistance, makes the device well-suited for use in battery operated systems.

In addition to its primary application of voltage references, the LM4040BIZ-2.5 is also well suited for temperature sensing applications. The device\'s low power consumption and wide operating temperature range make it well-suited for use in automotive and industrial temperature sensing applications.
