Precision Micropower Shunt Voltage Reference
General Description
Ideal for space critical applications, the LM4040 precision
voltage reference is available in the sub-miniature SC70 and
SOT-23 surface-mount package. The LM4040's advanced
design eliminates the need for an external stabilizing capac-
itor while ensuring stability with any capacitive load, thus
making the LM4040 easy to use. Further reducing design ef-
fort 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 LM4040-10.0. 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°C.
Bandgap reference temperature drift curvature correction and
low dynamic impedance ensure stable reverse breakdown
voltage accuracy over a wide range of operating tempera-
tures and currents.
Also available is the LM4041 with two reverse breakdown
voltage versions: adjustable and 1.2V. Please see the
LM4041 data sheet.
