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 refer-  
ence for 14, 16, or 18 bit data converters which re-  
quire an external precision reference. The device  
is also ideal for calibrating scale factor on high  
resolution data converters. The VRE3050 offers  
superior performance over monolithic references.  
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 exter-  
nal capacitor can be attached between the noise re-  
duction pin and the ground pin.
