VRE3050 – +5V, Low Noise Precision Voltage Reference

The VRE3050 is alow cost, zener-based precision voltage reference that provides ultra stable 5V output with ±0.5mV (.01%) initial accuracy. This improvement in accuracy is made possible by a unique proprietary multipoint laser compensation technique. The device also features a buried zener for low noise and excellent long term stability.

Temperature coefficients are as low as 0.6ppm/°C over the full industrial (0°C to 70°C) or hi-rel industrial (-40°C to 85°C) temperature range depending on the model and grade. This series is housed in a surface mount 8-pin package to provide maximum long term stability. This series is recommended for use as references for 14, 16, or 18 bit D/A converters which require an external precision reference. The device is also ideal for calibrating scale factor on high resolution A/D converters.
