SELECTION GUIDE
VRE120 series references are designed to operate
over an extremely wide temperature range (-55°C
to +180°C) and still provide excellent accuracy.
The VRE120 provides a +10V output, the VRE121
provides a -10V and the VRE122 provides a ±10V
output. All types are available in commercial (C
suffix) and military (M suffix) models. The "M"
models are screened for high reliability and quality.
Two accuracy grades (standard and "A") are
available for all models.
The adjacent selector guide shows the limits of the
most important parameters of the VRE120 series
voltage
references.
The
deviation increases linearly with temperature from
the 150°C specification to the 180°C specification.
For example, the A grade maximum voltage
deviation of 1mV increases to 2mV at 175°C and is
3mV at 180°C. This degree of accuracy over such
a large temperature range has been achieved
using the Thaler Corporation patented multipoint
compensation technique.
All devices are packaged in 14-pin hermetic ceramic packages for maximum long term stability. They are pin
and function compatible with other Thaler references and AD2700, AD2710 and MAX 670/671 References
