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).
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
