ADR421 General Description
The ADR42x series are ultraprecision second-generation XFET voltage references featuring low noise, high accuracy, and excellent long-term stability in a SOIC and Mini_SOIC footprints. Patented temperature drift curvature correction technique and XFET (eXtra implanted junction FET) technology minimize nonlinearity of the voltage change with temperature. The XFET architecture offers superior accuracy and thermal hysteresis to the bandgap references. It also operates at lower power and lower supply headroom than the Buried Zener references.
The superb noise, stable, and accurate characteristics of ADR42x make them ideal for precision conversion applications such as optical network and medical equipment. The ADR42x trim terminal can also be used to adjust the output voltage over a ±0.5% range without compromising any other performance. The ADR42x series voltage references offer two electrical grades and are specified over the extended industrial temperature range of 40°C to +125°C. Devices are available in 8-lead SOIC-8 or 30% smaller 8-lead Mini_SOIC-8 packages.
