LMC6001-MIL中文资料超低输入电流放大器数据手册TI规格书

描述 Description

Featuring 100% tested input currents of 25 fA maximum, low operating power, and ESDprotection of 2000 V, the LMC6001-MIL device achieves a new industry benchmark for low inputcurrent operational amplifiers. By tightly controlling the molding compound, Texas Instruments isable to offer this ultra-low input current in a lower cost molded package.
To avoid long turnon settling times common in other low input current opamps, the LMC6001A is tested three times in the first minute of operation. Even units that meet the25-fA limit are rejected if they drift.
Because of the ultra-low input current noise of 0.13 fA/√Hz, theLMC6001-MIL can provide almost noiseless amplification of high resistance signal sources. Addingonly 1 dB at 100 kΩ, 0.1 dB at 1 MΩ and 0.01 dB or less from 10 MΩ to 2,000 MΩ, the LMC6001-MIL isan almost noiseless amplifier.
The LMC6001-MIL is ideally suited for electrometer applications requiring ultra-low inputleakage such as sensitive photodetection transimpedance amplifiers and sensor amplifiers. Becauseinput referred noise is only 22 nV/√Hz, the LMC6001-MIL can achieve highersignal to noise ratio than JFET input type electrometer amplifiers. Other applications of theLMC6001-MIL include long interval integrators, ultra-high input impedance instrumentationamplifiers, and sensitive electrical-field measurement circuits.
