Datasheet
FEATURES
• 2.048 V OUTPUT ± 0.205 mV (.01%)
• TEMPERATURE DRIFT: 0.6 ppm/°C
• LOW NOISE: 1.5
• INDUSTRY STD PINOUT- 8 PIN DIP OR
•EXCELLENT LINE REGULATION: 6ppm/V Typ.
• OUTPUT TRIM CAPABILITY
DESCRIPTION
The VRE302-6 is a low cost, high precision 2.5V
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 +2.048V output
with ±0.205 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 VRE302-6 series
the most accurate reference available in the
standard 8 pin DIP package.
For enhanced performance, the VRE302-6 has an
external trim option for users who want less than
0.01% initial error.
provided to eliminate socket contact resistance
errors.

The VRE302-6 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 VRE302-
6 offers superior performance over monolithic
references.
