VRE4100 Series

Low Cost, SOIC-8

Precision References

DESCRIPTION

FEATURES

The VRE4100 is a low cost, high precision

bandgap reference that operates from +5V. The

device features low noise, digital error correction,

and an SOIC-8 package. The ultrastable output

is 0.05% accurate with a temperature coefficient

as low as 1.0 ppm/°C.

The improvement in

overall accuracy is made possible by using

EEPROM

registers

and

CMOS

DAC’s

for

temperature and initial error correction. The DAC

trimming is done after assembly which eliminates

assembly related shifts.

The VRE4100 is recommended for use as a

reference for 14, 16, or 18 bit data converters

which require a precision reference.

The

VRE4100

offers

superior

performance

over

standard on-chip references commonly found

with data converters.
