Description
The FAN4040 series of precision shunt references are ideal
for space- and cost-sensitive applications. They are available
in three output voltages (2.500V, 3.300V and 5.00V) and
with four output voltage tolerances (0.1%, 0.2%, 0.5% and
1%). They also have excellent temperature coefficients, to
100ppm/
°
C for the tighter tolerance grades. The FAN4040
series has an extended operating current range, sinking as
much as 25mA.
The FAN4040 series is available in SOT-23 package.
