DESCRIPTION

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 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 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. A

reference ground pin is provided to eliminate

socket contact resistance errors.

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.
