ADR421ARZ

The ADR421ARZ is an ultra-precision, second generation eXtra implanted junction FET (XFET) Voltage Reference 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 trim terminal can also be used to adjust the output voltage over a ±0.5% range without compromising any other performance.
