VRE305
Precision Voltage Reference  
FEaTuRES  
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.  
♦ +5 V Output, ± 0.5 mV (.01%)  
Temperature Drift: 0.6 ppm/ºC  
♦ Low Noise: 3 μVP-P (0.1-10Hz)  
♦ Industry Standard Pinout: 8-pin DIP or  
Surface Mount Package  
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.  
♦ Excellent Line Regulation: 6 ppm/V Typical  
♦ Output Trim Capability  
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.  
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 reduction  
pin and the ground pin. A reference ground pin is pro-  
vided to eliminate socket contact resistance errors.
