VRE302JD - Precision Voltage Reference, +2.5V, 0.40mV, -40ºC to +85ºC
The VRE302 is a low cost, high precision +2.5 V reference. Packaged in the industry standard 8-pin DIP, the device is ideal for upgrading systems that use lower performance references. The device provides ultrastable +2.5 V output with ±0.25 mV (.01%) initial accuracy and a temperature coefficient of 0.6 ppm/ºC.
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 VRE302 series the most accurate reference available in the standard 8-pin DIP package. For enhanced performance, the VRE302 has an external trim option for users who want less than 0.01% initial error. A reference ground pin is provided to eliminate socket contact resistance errors.
APPLICATIONS
The VRE302 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. The VRE302 offers superior performance over monolithic references.
