Voltage Comparators
General Description
The LF111 LF211 and LF311 are FET input
voltage comparators that virtually eliminate input current errors Designed 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 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 ‘‘applicatio...
