LMC6001
Ultra Ultra-Low Input Current Amplifier
General Description
Featuring 100% tested input currents of 25 fA max., low op-
erating power, and ESD protection of 2000V, the LMC6001
achieves a new industry benchmark for low input current op-
erational amplifiers. By tightly controlling the molding com-
pound, National is able to offer this ultra-low input current in
a lower cost molded package.
To avoid long turn-on settling times common in other low in-
put current opamps, the LMC6001A is tested 3 times in the
first minute of operation. Even units that meet the 25 fA limit
are rejected if they drift.
Because of the ultra-low input current noise of 0.13 fA/
√
Hz,
the LMC6001 can provide almost noiseless amplification of
high resistance signal sources. Adding only 1 dB at 100 k
,
0.1 dB at 1 M
and 0.01 dB or less from 10 M
to 2,000 M
,
the LMC6001 is an almost noiseless amplifier.
The LMC6001 is ideally suited for electrometer applications
requiring ultra-low input leakage such as sensitive photode-
tection transimpedance amplifiers and sensor amplifiers.
Since input referred noise is only 22 nV/
√
Hz, the LMC6001
can achieve higher signal to noise ratio than JFET input type
electrometer amplifiers. Other applications of the LMC6001
include long interval integrators, ultra-high input impedance
instrumentation amplifiers, and sensitive electrical-field mea-
surement circuits.
