... DESCRIPTION The VRE305 is a low cost, high precision +5 V refer- ence. 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 coeffi- cient of 0.6 ppm/° ...

... This network is less than 2% of the overall network resistance so it has a negligible effect on long term stability. The proper connection of the VRE305 series voltage references with the optional trim resistor for initial error and the optional capacitor for noise reduction is shown below. The VRE305 reference has the ground terminal brought out on two pins (pin 4 and pin 7) which are connected together internally ...
