VRE405

The VRE405 is a low cost, high precision, ±5 V reference. Available in 14-pin DIP or SMT packages, the device is ideal for new designs that need a high performance reference. The device provides ultrastable ±5 V output with ±0.5 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.

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 the reference ground errors.

Applications

The VRE405 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 VRE405 offers superior performance over monolithic references.
