The LF111, LF211 and LF311 are FET input voltage com- parators that virtually eliminate input current errors. De- signed to operate over a 5.0V to g15V range the LF111 can be used in the most critical applications.
The extremely low input currents of the LF111 allows the use of a simple comparator in applications usually requiring input current buffering. Leakage testing, long time delay cir- cuits, charge measurements, and high source impedance voltage comparisons are easily done.
Further, the LF111 can be used in place of the LM111 elimi-nating errors due to input currents. See the ''application hints'' of the LM311 for application help.
If Military/Aerospace specified devices are required,please contact the National Semiconductor Sales Office/Distributors for availability and specifications.
