DESCRIPTION
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.
FEATURES
♦ ±5 V Output, ± 0.5 mV (.01%)
♦ Temperature Drift: 0.6 ppm/ºC
♦ Low Noise: 3 μVP-P (0.1-10hz)
♦ Tracking Error: 0.3 mV Max.
♦ Excellent Line Regulation: 6 ppm/V Typical
♦ Surface Mount and DIP Package Options
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.
