LM4040/4041
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 the available in xed reverse breakdown voltages of 2.500V, 4.096V and 5.000V. The LM4041 is available with a xed 1.225V or an adjustable reverse breakdown voltage. The minimum operating current ranges from 60A for the LM4041-1.2 to 74A 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.
