The LM4041 series of shunt voltage references are versatile, easy-to-use references suitable for a wide array of
applications. They require no external capacitors for operation and are stable with all capacitive loads.
Additionally, the reference offers low dynamic impedance, low noise, and a low temperature coefficient to ensure
a stable output voltage over a wide range of operating currents and temperatures. The LM4041 uses fuse and
Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from
0.1% (max) for the A grade to 1% (max) for the D grade. Thus, a great deal of flexibility is offered to designers in
choosing the best cost-to-performance ratio for their applications. The LM4041 is available in a fixed (1.225 V
nominal) or an adjustable version (which requires an external resistor divider to set the output to a value between
1.225 V and 10 V).
