DESCRIPTION
The VRE304-6 is a low cost, high precision
4.096V reference.
standard 8 pin DIP, the device is ideal for
upgrading systems that use lower performance
references.
The device provides ultrastable +4.096V output
with ±0.409 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 VRE304-6 series
the most accurate reference available in the
standard 8 pin DIP package.
For enhanced performance, the VRE304-6 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 VRE304-6 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 VRE304-
6 offers superior performance over monolithic
references.
