DESCRIPTION
The VRE304-6 is a low cost, high precision
4.096V 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 +4.096V output
with 鹵0.409 mV (.01%) initial accuracy and a
temperature coefficient of 0.6 ppm/擄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 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.
A
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.
