REF3325AIDCKTG4 is a precision voltage reference family for PMIC (power management integrated circuit) applications. This reference family combines high accuracy and long-term stability with a wide operating temperature range up to 165-degrees Celsius (CELs) to satisfy performance requirements for the industrial and automotive markets. The device is available in a variety of packages including SOIC, DFN, and TO-220 to suit user requirements.

The REF3325AIDCKTG4 family provides a wide-voltage-range solution with a programmable output voltage that allows flexibility to customize the solution for any application. Output voltage levels can be configured via an external voltage divider which allows an external reference pin to be set to the desired output voltage. The reference family also allows for both higher current- and higher power-requirements. This feature makes them ideal for load regulation and serves as a reliable voltage supply for a wide range of equipment.

The programmable output voltage of the REF3325AIDCKTG4 family further improves the precision of the device’s voltage reference, extending its accuracy up to ±0.2%. In addition, its low noise and low temperature coefficient improve its overall performance. This feature allows the device to be used in difficult and precise circuit-level applications.

Also, the REF3325AIDCKTG4 family features an integrated window comparator to detect if the output voltage is outside of the pre-defined limits and an output buffer to drive an external load, therefore making it less dependent on host controller supply.

When it comes to the working principle of REF3325AIDCKTG4 family, the device uses a bandgap voltage reference to provide a stable, precise voltage reference. The bandgap voltage reference is created by combining two currents of different temperatures, thus creating a precise reference voltage regardless of the environmental conditions. The bandgap voltage reference is combined with a voltage error amplifier and a temperature compensation circuit to further enhance accuracy and long-term stability.

In conclusion, REF3325AIDCKTG4 family is an ideal power management integrated circuit for voltage references, delivering high accuracy and long-term stability with its wide operating temperature range, programmable output voltage and integrated window comparator. It is suitable for many applications such as load regulation, equipment power supplies and circuit-level applications.
