VRE304DS
DESCRIPTION
The VRE304 is a low cost, high precision +4.5 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 +4.5 V output with
±0.45 mV (.01%) initial accuracy and a temperature
coefficient of 0.6 ppm/°C. 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.
For enhanced performance, the VRE304 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.

The VRE304 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 VRE304 offers su-
perior performance over monolithic references.
