Description
Ideal for space critical applications, the LM4040CIM7X-4.1 is a precision voltage reference available in the subminiature (3mm × 1.3mm) SOT-23 surface-mount package. It is part of the LM4040 and LM4041 series. The LM4040 is available in fixed reverse breakdown voltages of 2.500V, 4.096V, and 5.000V, while the LM4041 is available with a fixed 1.225V or an adjustable reverse breakdown voltage. The minimum operating current ranges from 60µA to 74µA, depending on the specific version. The LM4040 has a maximum operating current of 15mA, while the LM4041 has a maximum operating current of 12mA. Both models 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.
