    ... 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. ...

    ... COMPENSATING FOR INPUT CAPACITANCE It is quite common to use large values of feedback resistance for amplifiers with ultra-low input current, like the LMC6001. Although the LMC6001 is highly stable over a wide range of operating conditions, certain precautions must be met to achieve the desired pulse response when a large feedback resistor is used ...

    ... SCR effects. The (I/O) input and output pins look similar to the gate of the SCR. There is a minimum cur- rent required to trigger the SCR gate lead. The LMC6001 is designed to withstand 100 mA surge current on the I/O pins. Some resistive method should be used to isolate any capac- 1188709 itance from supplying excess current to the I/O pins ...

    ... MΩ and 1000 MΩ. Because of this high value very important that the amplifier input currents be as small as pos- sible. The LMC6001 with less than 25 fA input current is an ideal choice for this application. The theoretical output of the standard Ag/AgCl pH probe is 59.16 mV/pH at 25° ...
