VRE304-6

Low Cost

Precision Reference

DESCRIPTION

FEATURES

The VRE304-6 is a low cost, high precision

4.096V 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 +4.096V output

with ±0.409 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

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 VRE304-6 series

the most accurate reference available in the

standard 8 pin DIP package.

For enhanced performance, the VRE304-6 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.

reference ground pin is provided to eliminate

socket contact resistance errors.

PIN CONFIGURATION

The VRE304-6 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 VRE304-

6 offers superior performance over monolithic

references.
