DESCRIPTION

The VRE305 is a low cost, high precision +5 V reference. Packaged in an industry standard 8-pin DIP or SMT, the device is ideal for upgrading systems that use lower performance references.

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. 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 VRE305 series the most accurate reference available in a standard 8-pin DIP or SMT.

FEATURES

♦ +5 V Output, ± 0.5 mV (.01)

♦ Temperature Drift: 0.6 ppm/ºC

♦ Low Noise: 3 μVP-P (0.1-10Hz)

♦ Industry Standard Pinout: 8-pin DIP or Surface Mount Package

♦ Excellent Line Regulation: 6 ppm/V Typical

♦ Output Trim Capability

APPLICATIONS

The VRE305 is recommended for use as a reference for 14, 16, or 18 bit D/A converters which require an external precision reference. The device is also ideal for calibrating scale factor on high resolution A/D converters. The VRE305 offers superior performance over monolithic references.
