The device is also ideal for calibrating scale factor on high resolution data converters. The VRE3021 offers superior performance over monolithic references. SELECTION GUIDE Initial Error mV 0.205 0.307 0.410 0.205 0.307 0.410 The VRE3021 is a low cost, high precision 2.048V reference that operates from +10V. The device features a buried zener for low noise and excellent long term stability. Packaged in an 8 pin DIP and SMT, the device is ideal for high resolution data conversion systems. The device provides ultrastable +2.048V output with ±0.2048 mV (.01%) initial accuracy and a temperature coefficient of 0.6 ppm/°C. This improvement in accuracy is made possible by a unique, patented multipoint laser compensation technique developed by Thaler Corporation. Si...
