Working Principle of The REF5025AIDG4

The REF5025AIDG4 is a voltage reference designed to provide a constant, low-offset voltage. It operates in a variety of frequencies, from 2.5V to 25V, and is suitable for very low-power applications. The main component of the REF5025AIDG4 is a bandgap reference circuit, which produces a predetermined output voltage with high accuracy, regardless of temperature or supply voltage. The output voltage is adjusted by changing the current in the active leg of the bandgap circuit.

The bandgap reference circuit consists of an active diode and two transistors. The active diode is designed to accurately maintain the same voltage across itself regardless of temperature. The transistors are used as current sources, and the voltage across the active diode is converted to a current which is sent to a resistance, creating a reference voltage. The reference voltage is then compared to a voltage divider, and the current of the active leg of the bandgap is adjusted accordingly.

The REF5025AIDG4 takes advantage of an advanced technology – trimmed resistor ladders – which allows for precise voltage references in a small package. It provides an accuracy of 5mV, at a maximum current of 50µA, and a low offset of 10mV. Its operating temperature range is -40°C to +125°C.

Conclusion

The REF5025AIDG4 Voltage Reference from Texas Instruments is a low-power, low-offset voltage reference IC designed for applications where accuracy and power efficiency are a priority. It has a range of frequency from 2.5V to 25V, and a wide operating temperature range. The REF5025AIDG4 is suitable for many applications, including consumer and industrial electronics, computers, automotive, test and measurement systems, and more. Its precise voltage reference and low-power operation make it an ideal solution for power management and voltage referencing in digital systems.
