Voltage Reference modules are widely used in industries to ensure the accuracy of the biasing DC power supply and the proper operation of specific components, and the 5962-89824PAPA module is no different. This module is mainly used in communication systems and aerospace equipment. The module is a three-terminal device that provides a stable DC voltage reference, accurate over temperature and wide supply voltage range. The external circuitry used which was incorporated in the 5962-89824PAPA to further increase the accuracy, while maintaining the temperature stability. It is a combination of a precision voltage reference and a temperature compensating voltage reference.

This 5962-89824PAPA module offers an excellent temperature coefficient of ±50ppm/°C, which is typically higher than that of discrete diodes used for voltage references. This result means that the module is well suited in applications where temperature stability is essential, such as in high-performance analog-to-digital applications. In addition, it also features a wide supply voltage range of 6 to 18 volts, allowing it to be used in a variety of operating conditions.

When using the 5962-89824PAPA module in an application, a number of measures should be taken to ensure its proper operation. For example, it should be placed close to the device that requires the voltage reference to ensure good thermal contact, as this will increase the accuracy of the module’s output. Also, a proper soldering of components should be undertaken to reduce the risk of short-circuit failures. Lastly, the module should be connected to the power supply in a manner that does not induce potential noise issues.

The 5962-89824PAPA module is powered with a DC voltage source and it provides a regulated voltage reference. The working principle of the module can be explained by the internal circuit design. The module contains a precision voltage reference, a temperature compensating device, and an buffer amplifier. The precision voltage reference is made up of a junction breakdown temperature controlled device, which is connected in a voltage divider circuit configuration. The voltage divider is composed of a pair of resistors, where the ratio of the two resistors is set to the desired reference voltage level. This reference voltage is fed to an external feedback network, which contains additional external components, such as resistors and capacitors, which are used to further stabilize the reference voltage and make it more accurate.

The temperature compensating device consists of a diode and a capacitor connected together in a voltage divider configuration. The ratio of the two components is set to the temperature coefficient of the device, which is typically ±50ppm/°C. This device compensates for the effect that temperature changes have on the reference voltage level, allowing for greater accuracy in temperature sensitive applications.

The buffer amplifier is used to provide isolation from the external components and other electrical noise sources. It is a non-inverting unity gain opamp configuration, which provides the required impedance level for driving the output of the module. The output voltage is further stabilized by a series of external capacitors, which reduce the ripple voltage, and further improve the accuracy of the reference voltage.

In conclusion, the 5962-89824PAPA module is a three-terminal device used in industry to ensure the accuracy of the biasing DC power supply and the proper operation of specific components, such as analog-to-digital converters. The module is powered with a DC voltage source, and it provides a regulated voltage reference that is accurate over temperature and wide supply voltage range. The module also features temperature compensating and noise reduction features, which make it well suited in applications requiring precision and temperature stability.
