DESCRIPTION

The VRE310 is a low cost, high precision +10 V refer-

ence. Available in an industry standard 8-pin DIP or

SMT, the device is ideal for upgrading systems that

use lower performance references.

The device provides ultrastable +10 V output with ±1.0

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 VRE310

series the most accurate reference available in a stan-

dard 8-pin DIP or SMT package.

For enhanced performance, the VRE310 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.

aPPlICaTIONS

The VRE310 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 VRE310 offers su-

perior performance over monolithic references.
