VRE405DS



DESCRIPTION

The VRE405 is a low cost, high precision, ±5 V refer-

ence. Available in 14-pin DIP or SMT packages, the

device is ideal for new designs that need a high perfor-

mance reference.

The device provides ultrastable ±5 V output with ±0.5

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 0.3 mV

maximum tracking error between the positive and neg-

ative output voltages over the operating temperature

range. This is extremely important in high performance

systems for reducing overall system errors.

For designs which use the DIP package in a socket,

there is a reference ground pin to eliminate the refer-

ence ground errors.

FEaTuRES

♦ ±5 V Output, ± 0.5 mV (.01%)

aPPlICaTIONS

The VRE405 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 ideal for calibrating scale factor on

high resolution A/D converters. The VRE405 of-

fers superior performance over monolithic refer-

ences.
