**About Analog Devices**
Analog Devices Inc. (ADI) is a global leader in high-performance semiconductor solutions, renowned for innovation in signal processing and power management technologies. With over 50 years of industry expertise, ADI sets benchmarks for precision, reliability, and quality across aerospace, automotive, and industrial sectors.

ADI’s rigorous testing protocols and cutting-edge manufacturing ensure consistent product excellence. Their voltage references are trusted worldwide for critical applications where accuracy and stability are non-negotiable, reinforcing ADI’s reputation as a pioneer in analog technology.

**About Voltage References**
Voltage references generate stable, precise DC voltages unaffected by temperature fluctuations, supply variations, or load changes. They serve as calibration anchors in electronic systems, ensuring measurement accuracy and signal integrity. Without high-quality references, sensitive circuitry like ADCs, sensors, and regulators would deliver unreliable performance.

In precision systems, voltage references directly impact overall accuracy. The ADR4525BRZ exemplifies this critical function with its sub-ppm stability and microvolt-level noise—making it indispensable for designs demanding uncompromised precision across environmental extremes.

Available in Tube packaging. Contact PCX for Tape & Reel or custom packaging requirements.

**FAQs**
**Q: What distinguishes series voltage references from shunt types?**
A: Series references (like the ADR4525BRZ) operate in series with the load, offering superior power efficiency and stability. Shunt references act as voltage-dependent resistors.

**Q: Can this IC drive capacitive loads?**
A: Yes, the ADR4525BRZ is stable with capacitive loads up to 10µF without external compensation.

**Q: Is the output voltage adjustable?**
A: No, this is a fixed 2.5V output reference. For adjustable options, see ADI’s ADR43x series.

**Q: Does the 950µA supply current include output load current?**
A: No. Supply current is independent of load current. Total system current = supply current (950µA) + load current.

**Q: Is this suitable for automotive applications?
