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.
