LM4040xxx Precision Micropower Shunt Voltage Reference
1 Features 3 Description
The LM4040 series of shunt voltage references are
1
• Fixed Output Voltages of 2.048 V, 2.5 V, 3 V,
versatile, easy-to-use references that cater to a vast
4.096 V, 5 V, 8.192 V, and 10 V
array of applications. The 2-pin fixed-output device
• Tight Output Tolerances and Low Temperature
requires no external capacitors for operation and is

stable with all capacitive loads. Additionally, the
reference offers low dynamic impedance, low noise,
– Max 0.1%, 100 ppm/°C – A Grade
and low temperature coefficient to ensure a stable
