DESCRIPTION
The VRE3041 is a low cost, high precision 4.096V 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 +4.096V output with ±0.4096 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. 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 VRE3041 series the most accurate reference available. For enhanced performance, the VRE3041 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. The VRE3041 is recommended for use as a reference for 14, 16, or 18 bit data converters which require an external precision reference. The device is also ideal for calibrating scale factor on high resolution data converters. The VRE3041 offers superior performance over monolithic references. SELECTION GUIDE Initial Error mV

Line Regulation Notes:
VOUT/ VIN
1) The specified values are without external trim. 2) The temperature coefficient is determined by the box method. See discussion on temperature performance. 3) Line and load regulation are measured with pulses and do not include voltage changes due to temperature. 4) Hysterisis measured over the operating temperature range.
