Product Summary

Ideal for space critical applications, the LM4040AIM3X-2.0 precision voltage reference is available in the sub-miniature SC70 and SOT-23 surface-mount package. The LM4040AIM3X-2.0 advanced design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4040AIM3X-2.0 easy to use. Further reducing design effort is the availability of several fixed reverse breakdown voltages: 2.048V, 2.500V, 3.000V, 4.096V, 5.000V, 8.192V, and 10.000V. The minimum operating current increases from 60 μA for the LM4040-2.5 to 100 μA for the LM4040AIM3X-2.0. All versions have a maximum operating current of 15 mA. The LM4040 utilizes fuse and zener-zap reverse breakdown voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.1% (A grade) at 25℃. Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents. Also available is the LM4041 with two reverse breakdown voltage versions: adjustable and 1.2V.
