VRE3050  
Precision Voltage Reference  
FEaTuRES  
DESCRIPTION  
The VRE3050 is a low cost, high precision 5 V refer-  
ence that operates from +10 V. The device features  
a buried zener for low noise and excellent long term  
stability. Packaged in an 8-pin SMT, the device is ideal  
for high resolution data conversion systems.  
♦ +5 V Output, ± 0.5 mV (.01%)  
Temperature Drift: 0.6 ppm/ºC  
♦ Low Noise: 3 μVP-P (0.1Hz-10Hz)  
♦ Low Thermal Hysterisis: 1 ppm Typical  
♦ ±15mA Output Source and Sink Current  
♦ Excellent Line Regulation: 5 ppm/V Typical  
♦ Optional Noise Reduction and Voltage Trim  
♦ Industry Standard Pinout: 8-pin 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 reg-  
ulation, and long-term stability, making the VRE3050  
series the most accurate reference available.  
aPPlICaTIONS  
The VRE3050 is recommended for use as a ref-  
erence for 14, 16, or 18 bit data converters which  
require an external precision reference. The de-  
vice is also ideal for calibrating scale factor on  
high resolution data converters. The VRE3050  
offers superior performance over monolithic ref-  
erences.  
For enhanced performance, the VRE3050 has an ex-  
ternal trim option for users who want less than 0.01%  
initial error. For ultra low noise applications, an external  
capacitor can be attached between the noise reduction  
pin and the ground pin.
