FEATURES
• 4.500 V OUTPUT ± 0.450 mV (.01%)
• TEMPERATURE DRIFT: 0.6 ppm/°C
• LOW NOISE: 3
• INDUSTRY STD PINOUT- 8 PIN DIP OR
•EXCELLENT LINE REGULATION: 6ppm/V Typ.
• OUTPUT TRIM CAPABILITY
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%
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.

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.

... This network is less than 2% of the overall network resistance so it has a negligible effect on long term stability. Figure 3 shows the proper connection of the VRE304 series voltage references with the optional trim resistor for initial error and the optional capacitor for noise reduction. The VRE304 reference has the ground terminal brought out on two pins (pin 4 and pin 7) which are connected together internally ...
