The ADR421AR from Analog Devices Inc. is a second-generation XFET voltage reference designed for high-accuracy applications. It offers a precise 2.5V output voltage with a low noise level of 1.75 μV p-p (0.1 Hz to 10 Hz).
Key electrical specifications include a low temperature coefficient of 3 ppm/°C, load regulation of 70 ppm/mA, and line regulation of 35 ppm/V. The device operates over a wide temperature range of -40°C to +125°C and has a quiescent current of 0.5 mA maximum.
Available in both 8-lead SOIC and 8-lead MSOP packages, the ADR421AR is suitable for surface-mount applications. Its high accuracy and stability make it ideal for precision data acquisition systems, high-resolution converters, and battery-powered instrumentation.
The patented temperature drift curvature correction technique and XFET technology minimize nonlinearity, providing superior accuracy and thermal hysteresis compared to band gap references.
