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.
