LM9140

Precision Micropower Shunt Voltage Reference

n Tolerates capacitive loads

n Fixed reverse breakdown voltages of 2.500V, 4.096V,

5.000V, and 10.000V

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.

Key Specifications

(LM9140-2.5)

n Temperature coefficient:

n Output voltage tolerance:

25 ppm/˚C (max)

0.5% (max)

n Low output noise (10 Hz to 10 kHz): 35 µV_rms(typ)

n Wide operating current range: 60 µA to 15 mA

n Industrial temperature range: −40˚C to +85˚C

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 25˚C.

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.
