DESCRIPTION
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.
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.
VRE4100 offers superior performance over
standard on-chip references commonly found
with data converters.
