VRE310

Low Cost

Precision Reference

DESCRIPTION

FEATURES

The VRE310 is a low cost, high precision 10.0V

reference. Packaged in the industry standard 8

pin DIP, the device is ideal for upgrading systems

that use lower performance references.

The device provides ultrastable +10.000V output

with ±1.000 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.

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 VRE310 series the

most accurate reference available in the standard

8 pin DIP package.

For enhanced performance, the VRE310 has an

external trim option for users who want less than

0.01% initial error.

For ultra low noise

applications, an external capacitor can be

attached between the noise reduction pin and the

ground pin. A reference ground pin is provided to

eliminate socket contact resistance errors.

PIN CONFIGURATION

The VRE310 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 VRE310

offers superior performance over monolithic

references.
