• High current stability (60µA)

Application Field

The LM4040D20IDCKR reference voltage can be used in many different applications, including power supply design, motor control, audio and video systems, security systems, medical electronics, automotive electronics, industrial process controls, and computer peripherals. The reference voltage can also be used to provide voltage regulation in regulated power supplies, adjustable charge pump circuits, standby power supplies, filter circuits, linear current regulators, and low voltage LCD displays.

The LM4040D20IDCKR reference voltage can also provide stability and accuracy in process controls such as temperature sensing, spike protection, and level detecting circuits. This type of reference voltage is especially useful in sensor voltage isolation and closed-loop feedback circuits.

Working Principle

The working principle of the LM4040D20IDCKR reference voltage is based on temperature-compensated bandgap technology. This technology is used to sense and control the voltage reference point and then regulate the output voltage around that reference point. The LM4040D20IDCKR is designed to provide a very accurate voltage referencepoint without the need for external trimming.

The internal compensation network monitors the temperature changes of the die and compensates for them using an internal circuitry. This ensures that the reference voltage remains constant over different temperature ranges. The LM4040D20IDCKR is able to do this with low quiescent current (35 µA) and low drift (2-25ppm/°C).

The reference voltage is adjustable and can be set to any value between 2.2V and 16V. The output of the reference is protected against overvoltage and reverse-polarity protection. The reference can also be programmed with a current source or sink output using an external resistor.

Conclusion

The LM4040D20IDCKR is an adjustable voltage reference designed to provide a reliable and highly accurate reference voltage. It has an ultra-low power consumption and is able to operate over a wide range of supplies. It features an extremely accurate temperature coefficient and very low reference noise. The reference is protected against overvoltage and reverse-polarity protection, making it ideal for a wide range of applications.
