DESCRIPTION

The VRE3050 is a low cost, high precision 5 V reference 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.

The device provides ultrastable +5 V output with ±0.5 mV (.01%) initial accuracy and a temperature coefficient 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 VRE3050 series the most accurate reference available.
