6 / 20 page VRE404 Precision Dual Reference DESCRIPTION FEATURES The VRE404 is a low cost, high precision, ±4.5V reference. Packaged in 14 pin DIP or SMT packages, the device is ideal for new designs that need a high performance reference. The device provides ultrastable ±4.500V output with ±0.450 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. Another key feature of this reference is the 0.3 mV maximum tracking error between the positive and negative output voltages over the operating temperature range. This is extremely important in high performance systems for reducing overall system errors. For designs which use the DIP package in a socket, there is a reference ground pin to eliminate reference ground errors. The VRE404 is recommended for use as a reference for high precision D/A and A/D converters which require an external precision reference. The device is ideal for calibrating scale factor on high resolution A/D converters. The VRE404 offers superior performance over monolithic references. • ±4.500 V OUTPUT ± 0.400 mV (.01%) • TEMPERATURE DRIFT: 0.6 ppm/°C • LOW NOISE: 3µVpp (0.1-10Hz) • TRACKING ERROR: 0.3 mV max. • EXCELLENT LINE REGULATION: 6ppm/V Typ. • SURFACE MOUNT AND DIP PACKAGES FIGURE 1 VRE404DS REV.
