DescriptionThe VRE505 is a low cost, high precision +5 V reference. The device is ideal for upgrading systems that use lower performance references.
The device VRE505 provides ultrastable +5 V output with ±0.5 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 VRE505 the most accurate reference available.
For enhanced performance, the VRE505 has an external trim option for users who want less than 0.01% initial error. For ultra low noise applications, an external capacitor can be attached between the noise reduction pin and the ground pin. A reference ground pin is provided to eliminate socket contact resistance errors.
Applications
The VRE505 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 VRE505 offers superior performance over monolithic references.
