VRE305
Precision Voltage Reference
VRE305
FEATURES
? +5 V Output, ± 0.5 mV (.01%)
? Temperature Drift: 0.6 ppm/oC
? Low Noise: 3 μV P-P (0.1-10Hz)
? Industry Standard Pinout: 8-pin DIP or

APPLICATIONS
The VRE305 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 VRE305 offers su-
perior performance over monolithic references.
DESCRIPTION
The VRE305 is a low cost, high precision +5 V refer-
ence. Packaged 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 +5 V output with ±0.5
mV (.01%) initial accuracy and a temperature coeffi-
cient of 0.6 ppm/°C. 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 VRE305
series the most accurate reference available in a stan-
dard 8-pin DIP or SMT.
For enhanced performance, the VRE305 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 reduc-
tion pin and the ground pin. A reference ground pin is
provided to eliminate socket contact resistance errors.
