GENERAL DESCRIPTION
The ADR42x are a series of ultraprecision, second generation
eXtra implanted junction FET (XFET) voltage references
featuring low noise, high accuracy, and excellent long-term
stability in SOIC and MSOP footprints.
Patented temperature drift curvature correction technique and
XFET technology minimize nonlinearity of the voltage change
with temperature. The XFET architecture offers superior
accuracy and thermal hysteresis to the band gap references. It
also operates at lower power and lower supply headroom than
the buried Zener references.
The superb noise and the stable and accurate characteristics
of the ADR42x make them ideal for precision conversion
applications such as optical networks and medical equipment.
The ADR42x trim terminal can also be used to adjust the out-
put 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 have
8-lead SOIC or 30% smaller, 8-lead MSOP packages.
