DESCRIPTION
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.
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. For ultra low noise applications,
an external capacitor can be attached between the
noise reduction pin and the ground pin.
reference ground pin is provided to eliminate
socket contact resistance errors.

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.
