DESCRIPTION
FEATURES
The VRE3025 is a low cost, high precision 2.5V
reference that operates from +10V.
The device
features a buried zener for low noise and excellent
long term stability. Packaged in an 8 pin DIP and
SMT, the device is ideal for high resolution data
conversion systems.
The device provides ultrastable +2.500V output
with ±0.2500 mV (.01%) initial accuracy and a
temperature coefficient of 0.6 ppm/°C.
This
improvement in accuracy is made possible by a
unique, patented multipoint laser compensation
technique
developed
by
Thaler
Corporation.
Significant improvements have been made in
other performance parameters as well, including
initial accuracy, warm-up drift, line regulation, and
long-term stability, making the VRE3025 series
the most accurate reference available.
For enhanced performance, the VRE3025 has an
external trim option for users who want less than
0.01%
initial
error.
For
ultra
low
noise
applications,
an
external
capacitor
can
be
attached between the noise reduction pin and the
ground pin.

PIN CONFIGURATION
The VRE3025 is recommended for use as a
reference for 14, 16, or 18 bit data converters
which require an external precision reference.
The device is also ideal for calibrating scale factor
on high resolution data converters. The VRE3025
offers
superior
performance
over
monolithic
references.
