The LM4040 series of shunt voltage references are versatile, easy-to-use references that cater to a vast array of
applications. The 2-pin fixed-output device requires no external capacitors for operation and is stable with all
capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low temperature
coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures. The
LM4040 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.
Packaged in space-saving SC-70 and SOT-23-3 packages and requiring a minimum current of 45 μ A (typ), the
LM4040 also is ideal for portable applications. The LM4040xI is characterized for operation over an ambient
temperature range of – 40 ° C to 85 ° C. The LM4040xQ is characterized for operation over an ambient temperature
range of – 40 ° C to 125 ° C.
