LM4040/LM4041
Precision Micropower Shunt
Voltage Reference
General Description
Ideal for space critical applications, the LM4040 and LM4041 precision
voltage references are available in the subminiature (3mm × 1.3mm) SOT-23 surface-mount package.
The LM4040 is available in fixed reverse breakdown
voltages of 2.500V, 4.096V, and 5.000V. The LM4041 is available with a fixed 1.225V or an adjustable reverse breakdown
voltage.
The minimum operating current ranges from 60μA for the LM4041-1.2 to 74μA for the LM4040-5.0. LM4040 versions have a maximum operating current of 15mA. LM4041 versions have a maximum operating current of 12mA.
The LM4040 and LM4041 have bandgap reference temperature drift curvature correction and low dynamic impedance, ensuring stable reverse breakdown
voltage accuracy over a wide range of operating temperatures and currents.
