Description
FTREF-01/FTREF-02
are precision 10V and 5V bandgap
references which provide stable output voltages over a
wide range of operating conditions. Output voltage is
accurate to
±0.3%
with a low 5ppm/°C typical temperature
coefficient. The
FTREF-01
and
FTREF-02
are excellent choices
for applications where low drift, moderate accuracy, low
power consumption and low cost are considerations.
The
FTREF-02
includes a temperature output pin which
provides a linear voltage proportional to absolute tem-
perature.
For lower drift and higher accuracy references, please see
the
FT1019
and
FT1021
data sheets.
