Applications
The VRE306 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 VRE306 offers su-
perior performance over monolithic references.
DESCRIPTION
The VRE306 is a low cost, high precision +6 V refer-
ence. Available in an industry standard 8-pin surface
mount package, the device is ideal for upgrading sys-
tems that use lower performance references.
The device provides ultrastable +6 V output with ±0.6
mV (.01%) initial accuracy and a temperature coeffi-
cient of 0.6 ppm/ºC. This improvement in accuracy is
made possible by a unique, patented multipoint laser
compensation technique. 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 VRE306
series the most accurate reference available in a stan-
dard 8-pin SMT package.
For enhanced performance, the VRE306 has an exter-
nal trim option for users who want less than 0.01% ini-
tial 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 pro-
vided to eliminate socket contact resistance errors.
