The accuracy of the VRE125/127 series over
VRE127MA ±5V ±0.6mV ±2.0mV ±0.4mV
temperature is achieved by using Thaler
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.
