aPPlICaTIONS

The VRE410 is recommended for use as a refer-

ence for high precision D/A and A/D converters

which require an external precision reference.

The device is also ideal for calibrating scale factor

on high resolution A/D converters. The VRE410

offers superior performance over monolithic refer-

ences.

DESCRIPTION

The VRE410 is a low cost, high precision, ±10 V refer-

ence. Available in a 14-pin SMT package, the device

is ideal for new designs that need a high performance

reference.

The device provides ultrastable ±10 V output with ±1.0

mV (.01%) initial accuracy and a temperature coeffi-

cient of 0.6 ppm/°C. This improvement in accuracy is

made possible by a unique, patented multipoint laser

compensation technique.

Another key feature of this reference is the 0.5 mV

maximum tracking error between the positive and neg-

ative output voltages over the full operating tempera-

ture range. This is extremely important in high perfor-

mance systems for reducing overall system errors.
