National Semiconductor LF111

The LF111 LF211 and LF311 are FET input voltage comparators that virtually eliminate input current errors Designed to operate over a 5 0V to g 15V 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 circuits charge measurements and high source impedance voltage comparisons are easily done Further the LF111 can be used in place of the LM111 eliminating errors due to input currents See the ‘‘application hints’’ of...
