The VRE125 provides a +5V output and the VRE127 provides a ±5V output. All types are available in mercial (C suffix) and military (M suffix) models. They are hermetically sealed and are screened for high reliability and quality. Two accuracy grades (standard and A) are available in both models. The adjacent selector guide shows the limits of the most important parameters of the VRE125/127 series references. SELECTION GUIDE Max. Volt Deviation (-55°C to +150°C) Max.

The stability of the VRE125 series is enhanced by using a zener diode instead of a bandgap reference, which is typically used in 5V references. Zener diodes have better long term stability and don't suffer the significant shifts caused by temperature cycling that bandgap references do. Other performance parameters, such as warm-up drift and long term stability are better than petitive models. Superior...
