LMC6001 Ultra Ultra-Low Input Current Amplifier
March 1995
LMC6001 Ultra Ultra-Low Input Current Amplifier
General Description
Featuring 100% tested input currents of 25 fA max., low operating power, and ESD protection of 2000V, the LMC6001 achieves a new industry benchmark for low input current operational amplifiers. By tightly controlling the molding compound, 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 input 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 photodetection 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 measurement circuits.
