APPLICATIONS
The VRE302 is recommended for use as a refer-
ence for 14, 16, or 18 bit D/A converters which re-
quire an external precision reference. The device
is also ideal for calibrating scale factor on high
resolution A/D converters. The VRE302 offers su-
perior performance over monolithic references.
DESCRIPTION
The VRE302 is a low cost, high precision +2.5 V refer-
ence. Packaged in the industry standard 8-pin DIP, the
device is ideal for upgrading systems that use lower
performance references.
The device provides ultrastable +2.5 V output with
±0.40 mV (.016%) initial accuracy and a temperature
coefficient of 1.0 ppm/oC. This improvement in accu-
racy is made possible by a unique, patented multipoint
laser compensation technique. Significant improve-
ments have been made in other performance param-
eters as well, including initial accuracy, warm-up drift,
line regulation, and long-term stability, making the
VRE302 series the most accurate reference available
in the standard 8-pin DIP package.
For enhanced performance, the VRE302 has an ex-
ternal trim option for users who want less than 0.01%
initial error. A reference ground pin is provided to elimi-
nate socket contact resistance errors.
