PMIC - Voltage Reference

The MAX6043AAUT50#TG16 is a voltage reference module, also known as a precision voltage reference or programmable reference. This type of device serves as a constant source of reference or reference voltage, used in applications such as electronic test equipment and digital-to-analog converters.

A voltage reference is a device used to maintain a given reference voltage. A precision voltage reference, like the MAX6043AAUT50#TG16, is a type of device used when a constant and accurate reference voltage needs to be maintained in a system. It is typically used to set the reference level for precision measurements, such as for converting an analog signal to digital form.

A voltage reference is comprised of an integrated circuit (IC) coupled to a reference voltage source. It has an input where the reference voltage is applied and an output where the reference voltage is maintained. The IC provides buffering and stabilization of the reference voltage so its level remains constant and accurate over time. In the case of the MAX6043AAUT50#TG16, it features a reference voltage of 5V and is capable of maintaining it to within 1mV accuracy over its lifetime.

Operating Principle

The MAX6043AAUT50#TG16 operates on the principle of the band-gap voltage reference, which is a type of precision voltage reference. It works by using voltage sources made out of diodes to form a voltage divider. The voltage developed across the base of the diodes is then compared to a reference voltage made from a p-n junction diode. When these voltages become equal, a steady state is reached and the output voltage is maintained to within its accuracy rating.

The MAX6043AAUT50#TG16 features a proprietary process cell correction technique, which further improves the accuracy of the reference voltage. This involves the application of pairs of voltage sources with a matched process coefficient. The sources are then matched to a see-saw adjustment of their output voltages while keeping their temperature coefficients equal.

Application Fields

The MAX6043AAUT50#TG16 is an ideal choice for a variety of applications, such as precision instrumentation, test equipment, and digital-to-analog converters. Its accuracy and stability make it suitable for use in medical devices, automotive electronics, and consumer electronics. Its small form factor makes it particularly suitable for applications where space is at a premium. This makes it the ideal choice for designs with limited space, such as embedded applications.

The MAX6043AAUT50#TG16 is also well suited for use in automated test equipment and factory automation. Its precision and stability make it ideal for setting reference voltages for testing circuit boards and components, as well as for controlling motor actuators and valves.

Conclusion

The MAX6043AAUT50#TG16 is a precision voltage reference, ideal for use in applications needing an accurate and stable reference voltage. It features a reference voltage of 5V and is accurate to within 1mV over its lifetime. It is widely used in instrumentation, test equipment, and digital-to-analog converter designs. It is also suitable for use in embedded and automated test equipment applications.
