The VRE304 is a low cost, zener-based precision voltage reference that provides ultra stable +4.5V output with ±0.90mV (.02%) initial accuracy. This improvement in accuracy is made possible by a unique proprietary multipoint laser compensation technique. Significant improvements have been made in other performance parameters, including warm-up drift, line regulation, and long-term stability, and make this series ideal for upgrading systems that use lower performance references.
Temperature coefficients are as low as 2.0ppm/°C over the full industrial (0°C to +70°C) temperature range. This VRE is recommended for use as a reference 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.
