Working Principle

The LM4041B12IDBZR operates as a bandgap voltage reference. It uses a bandgap circuit which references the voltage to a predetermined voltage level without being affected by changes in the power line voltage or temperature. The advantage of using a bandgap reference is that it has a very low temperature drift and is more stable than a zener diode.

The bandgap reference uses an N-type and a P-type transistor which create a double-diode structure. The difference in the amount of current flowing through each diode is proportional to the temperature difference. This difference is kept at a constant level by comparing it to the voltage developed between the reference terminals. Reducing the bias current of the die adjusts the output voltage which can be used as an input to an amplifier.

The LM4041B12IDBZR is designed for low voltage applications, hence the lower power dissipation. The internal circuitry is optimized to provide a fast response and system stability. This device also includes a low-noise amplifier which helps to improve the quality of the output signal.
