Apex Microtechnology VRE306 +6V Low Noise Precision Voltage Reference

Apex Microtechnology VRE306 +6V Low Noise Precision Voltage Reference is a low-cost, Zener-based precision voltage reference. The VRE306 has an ultrastable +6V output with ±0.6mV (.01%) initial accuracy. Accuracy improvement is possible by a multipoint laser compensation technique. Other significant improvements include warm-up drift, line regulation, and long-term stability. This makes this VRE ideal for upgrading systems that use lower performance references. Temperature coefficients are as low as 0.6ppm/°C over the full industrial (0°C to +70°C) temperature range. The VRE306 is housed in a surface mount 8-pin package.


  • +6V Output, ± 0.6mV (0.01%)
  • 0.6ppm/°C temperature drift
  • 4μVP-P (0.1-10 Hz) low noise
  • 8-pin Surface Mount Package industry standard pinout
  • 6ppm/V typical excellent line regulation 
  • Output trim capability


  • For use as a reference for 14-, 16-, or 18-bit D/A converters which require an external precision reference
  • Ideal for calibrating scale factor on high-resolution A/D converters
  • Offers superior performance over monolithic references.
