| www.fairchildsemi.com FAN4041 Precision Micropower Shunt Voltage Reference Features * * * * * * Adjustable shunt reference Tolerances to +0.5% (25C) Low output noise Low temperature coefficient to 100 ppm/C max Small packages Extended operating current range 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.
