LM9140
Precision Micropower Shunt Voltage Reference
General Description
The LM9140’s reverse breakdown voltage temperature coef-
ficients of
±
25 ppm/C are ideal for precision applications.
The LM9140’s advanced design eliminates the need for an
external stabilizing capacitor while ensuring stability with any
capacitive load, thus making the LM9140 easy to use. Fur-
ther reducing design effort is the availability of several fixed
reverse breakdown voltages: 2.500V, 4.096V, 5.000V, and
10.000V. The minimum operating current increases from
60 μA for the LM9140-2.5 to 100 μA for the LM9140-10.0. All
versions have a maximum operating current of 15 mA.
The LM9140 utilizes fuse and zener-zap reverse breakdown
voltage trim during wafer sort to ensure that the prime parts
have an accuracy of better than
±
0.5% (B grade) at 25C.
Bandgap reference temperature drift curvature correction
and low dynamic impedance ensure stable reverse break-
down voltage accuracy over a wide range of operating tem-
peratures and currents.
