DESCRIPTION
The VRE310 is a low cost, high precision 10.0V
reference. Packaged in the industry standard 8
pin DIP, the device is ideal for upgrading systems
that use lower performance references.
The VRE310 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 VRE310
offers superior performance over monolithic
references.
The device provides ultrastable +10.000V output
with ±1.000 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 VRE310 series the
most accurate reference available in the standard
8 pin DIP package.

For enhanced performance, the VRE310 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. A reference ground pin is provided to
eliminate socket contact resistance errors.
For package option add D for DIP or S for Surface Mount
to end of model number.
