The device is also ideal for calibrating scale factor on high resolution data converters. The VRE3025 offers superior performance over monolithic references. The VRE3025 is a low cost, high precision V reference that operates from +10 V. The device features a buried zener for low noise and excellent long term stability. Packaged in either an 8-pin DIP or SMT option, the device is ideal for high resolution data conversion systems. The device provides ultrastable V output with mV initial accuracy and a temperature coefficient of 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 VRE3025 series the most accurate reference available. For enhanced performance, the VRE3025 has an external trim option for users who want less than initial error. For ultra low noise applications, an external capacitor can be attached between the noise reduction pin and the ground pin. Figure BLOCK DIAGRAM R1 R2 SELECTION GUIDE Model Initial Error mV Temp.
