The ADR434BR from Analog Devices Inc. is a member of the XFET® voltage reference family, which utilizes patented temperature drift curvature correction and noise reduction technologies to offer a significant performance improvement over traditional bandgap and buried Zener references.
This high-precision voltage reference features a low output noise of only 1.0 µV p-p (0.1 Hz to 10 Hz), making it an excellent choice for high-resolution data converters and precision applications. With a long-term stability of 50 ppm/√kHr (typical), the ADR434BR ensures consistent performance over time.
The output voltage of 4.096 V is commonly used as a reference in many analog-to-digital conversion systems due to its compatibility with binary scaling. This makes the ADR434BR particularly well-suited for precision measurement and data acquisition systems where accuracy is paramount.
The ADR434BR also boasts a low temperature coefficient of 3 ppm/°C (max) over the extended industrial temperature range of −40°C to +125°C. This feature ensures minimal voltage variation in diverse operating conditions, which is critical for precision instruments and industrial applications.
The device comes in an 8-lead SOIC package, offering a compact solution for space-constrained applications. Its wide operating range of 5 V to 18 V and the ability to source up to 30 mA of output current make it flexible for various circuit designs. Additionally, the ADR434BR includes a trim terminal that allows fine-tuning of the output voltage to compensate for voltage drops in wired applications or to adjust the voltage for specific needs.
In summary, the ADR434BR is an ultra-precision, low noise, and stable voltage reference that is ideal for high-end instrumentation, precision data acquisition systems, and any application requiring a high degree of voltage accuracy and stability.
