Description
The FAN4040 series of precision shunt references are ideal
for space- and cost-sensitive applications. They are available
in two output voltages (2.500V and 3.300V) 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.
