ADR423 Description

The ADR423 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 ADR423 make them ideal for precision conversion applications such as optical networks and medical equipment. The ADR423 trim terminal can also be used to adjust the out-put voltage over a ±0.5% range without compromising any other performance. The ADR423 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.
