VRE3050

+5V, Low Noise Precision Voltage Reference

  • High accuracy – +5V output, ± 0.5mV (.01%)
  • Low Temperature drift – 0.6ppm/°C
  • Low noise – 3µVP-P (0.1Hz-10Hz)
  • Low thermal hysteresis – 1ppm typical
  • Output source and sink current – ±15mA
  • Excellent line regulation – 5ppm/V Typical
  • Optional noise reduction and voltage trim

The VRE3050 is a low 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-reliability 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.
