Power management regulating integrated circuits (PMIC) provide the crucial means for electronic systems to operate correctly by monitoring the supply voltages and maintaining a predetermined reference. A voltage reference is a special type of PMIC that regulates the output voltage to a predetermined level. This feature provides a voltage or current with a feedback loop that smoothes the output voltage or current over time. The REF5045AQDRQ1 voltage reference is a popular choice within this category, featuring a low-noise performance, wide temperature range, and multiple temperature configurations.

The REF5045AQDRQ1 is an ultra-low-noise, low-drift, fixed-output-voltage series of voltage references that are designed for high-performance applications. The device features an operating voltage range of 2.4V to 9.5V and an on-board adjustable output that can be set from 0 to 6V in 1mV increments. It also features low-drift and low-noise performance, and is designed to operate over a wide temperature range of -40°C to +125°C.

The REF5045AQDRQ1 is suitable for a variety of applications including instrumentation, robotics, medical, industrial, telecom and consumer electronics. It is specifically designed for use in industrial and consumer applications where accurate, low-noise reference voltages are required. It can also be used in precision and accurate low-noise circuit designs, such as low-noise amplifiers, audio-fidelity amplifiers and audio mixers. In addition, the REF5045AQDRQ1 can also be used as a precision voltage source and an accuracy/Harmonic input/output reference.

The REF5045AQDRQ1 is designed to provide a very low noise output voltage reference with a stable output voltage over temperature, process and time. It features a low temperature coefficient of 0.20ppm/°C (reference function) and a low noise of 7.5µVpp (reference function). The device features a buffered output and offers excellent PSRR and line regulation with a typical drift of 0.015mV/°C.

In addition, the REF5045AQDRQ1 uses a novel precision temperature-tracking architecture to ensure fast transient response, high noise immunity and good output accuracy. This architecture allows the output to track the temperature-induced noise over temperature and process variations. In other words, the output voltage will track the temperature and process variations within the specified limits. The device also provides excellent accuracy over a wide temperature range of -40°C to +125°C.

The REF5045AQDRQ1 is a versatile and robust voltage reference that can be used in a wide range of applications. Due to its low-noise and low-drift performance, as well as its wide temperature range and ability to track temperature changes, it is a great choice for industrial and consumer applications that require a stable and accurate voltage reference.
