Corporation's patented multi-point compensation technique. 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 competitive
models.
Superior stability, accuracy, and quality make these references ideal for high temperature applications such
as A/D and D/A converter references.
VRE125 series references are designed to
operate over an extremely wide temperature
range (-55°C to +200°C) and still provide
excellent accuracy. The VRE125 provides a +5V
output and the VRE127 provides a ±5V output.
All types are available in commercial (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
VRE125/127 series references.
The accuracy of the VRE125/127 series over
temperature is achieved by using Thaler
