**ADR5044AKSZ-R2: A Precision 5V Voltage Reference for Demanding Applications**
In the world of precision electronics, the stability and accuracy of a voltage reference are paramount. They serve as the foundational cornerstone for systems where precise measurements are critical, such as in high-resolution data converters, precision analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and sophisticated industrial instrumentation. The **ADR5044AKSZ-R2** from Analog Devices stands out as a premier solution, engineered to deliver exceptional performance in the most demanding applications.
This voltage reference is designed to provide a fixed, stable **5V output** with remarkably low error. Its core architecture is based on the patented *"XFET" (eXtra implanted junction Field-Effect Transistor)* technology, which offers a unique combination of advantages over traditional bandgap or buried zener diode references. The XFET design inherently provides **lower noise**, **lower thermal hysteresis**, and a more stable output over time and temperature variations.
Key to its high-performance credentials are its impressive specifications. The ADR5044AKSZ-R2 boasts an initial accuracy of up to **±0.06% (0.6 mV)**, ensuring the system starts with a highly precise baseline. Perhaps even more critical is its exceptional temperature stability, characterized by a low **temperature coefficient (tempco) of 5 ppm/°C** maximum. This means the output voltage drifts minimally across the entire specified industrial temperature range (-40°C to +125°C), a vital feature for applications exposed to fluctuating environmental conditions.
Furthermore, the device exhibits excellent long-term stability, with a typical drift of **50 ppm/1000 hours**, guaranteeing reliability and consistency over the product's lifespan. It requires only a minimal quiescent current of 240 µA, making it suitable for power-sensitive designs, and can source up to 10 mA of output current while sinking up to 2 mA. Its low output noise performance (4 µVp-p/V, 0.1 Hz to 10 Hz) ensures that it does not introduce significant noise into the signal chain it supports.
Housed in a space-saving **SOT-23-3 package**, the ADR5044AKSZ-R2 offers this high level of precision in a minimal footprint, making it an ideal choice for compact, portable, and high-density PCB designs. Whether it's powering the critical reference input of a 16-bit or 18-bit ADC, ensuring accuracy in automotive sensor systems, or providing a stable voltage in medical monitoring equipment, this component delivers unwavering performance.
**ICGOOODFIND**: The ADR5044AKSZ-R2 is a top-tier, high-precision voltage reference that masterfully balances accuracy, stability, low noise, and power efficiency. Its robust performance across temperature and time makes it an indispensable component for designers who cannot compromise on quality in their most critical and demanding applications.
