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 flexibilitis offered to designers in choosing the best cost-to-performance ratio for their applications.
