Low Cost
Precision Reference
DESCRIPTION
FEATURES
The VRE304 is a low cost, high precision 4.5V
reference. Packaged in the industry standard 8
pin DIP, the device is ideal for upgrading systems
that use lower performance references.
The device provides ultrastable +4.500V output
with ±0.4500 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 VRE304 series the
most accurate reference available in the standard
8 pin DIP package.
For enhanced performance, the VRE304 has an
external trim option for users who want less than
0.01%
initial
error.
applications, an external capacitor can be
attached between the noise reduction pin and the
ground pin. A reference ground pin is provided to
eliminate socket contact resistance errors.

PIN CONFIGURATION
The VRE304 is recommended for use as a
reference for 14, 16, or 18 bit D/A converters
which require an external precision reference.
The device is also ideal for calibrating scale
factor on high resolution A/D converters. The
VRE304 offers superior performance over
monolithic references.
