Applications
This series is recommended for use as a reference for
14, 16, or 18-bit data converters which require a preci-
sion reference. The series offers superior performance
over standard on-chip references commonly found
with data converters.
DESCRIPTION
The VRE4112/VRE4125/VRE4141 are low cost, high
precision bandgap references that operate from +5 V.
These devices feature low noise, digital error correc-
tion, and an SOIC-8 package. The ultra stable output
is 0.05% accurate with a temperature coefficient as
low as 1.0 ppm/ºC. The improvement in overall accu-
racy is made possible by using EEPROM registers and
CMOS DAC’s for temperature and initial error correc-
tion. The DAC trimming is done after assembly which
eliminates assembly related shifts.
