Description
The FAN4041 adjustable precision shunt references are ideal
for space- and cost-sensitive applications. They are available
with output voltage tolerances of 0.5% and 1%. They also
have excellent temperature coefficients, to 100ppm/
C for
the tighter tolerance grades. The FAN4041 series has an
extended operating current range, sinking as much as 25mA.
The FAN4041 series is available in SOT-23 and TO-92
packages.
