Ideal for space critical applications, the LM4040CEM3-2.5/NOPB(购买请点击) precisionvoltage reference is available in the sub-miniature SC70 andSOT-23 surface-mount package. The LM4040’s advanceddesign eliminates the need for an external stabilizing capacitorwhile ensuring stability with any capacitive load, thusmaking the LM4040CEM3-2.5/NOPB easy to use. Further reducing designeffort is the availability of several fixed reverse breakdownvoltages: 2.048V, 2.500V, 3.000V, 4.096V, 5.000V, 8.192V,and 10.000V. The minimum operating current increases from60 μA for the LM4040-2.5 to 100 μA for the LM4040CEM3-2.5/NOPB -10.0. Allversions have a maximum operating current of 15 mA.
The LM4040CEM3-2.5/NOPB(购买请点击) utilizes fuse and zener-zap reverse breakdownvoltage trim during wafer sort to ensure that the prime partshave an accuracy of better than ±0.1% (A grade) at 25°C.Bandgap reference temperature drift curvature correctionand low dynamic impedance ensure stable reverse breakdownvoltage accuracy over a wide range of operating temperaturesand currents.
Also available is the LM4040CEM3-2.5/NOPB(购买请点击) 1 with two reverse breakdownvoltage versions: adjustable and 1.2V. Please see theLM4041 data sheet.
