LF111 LF211 LF311 Voltage Comparators
General Description
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
Features
Y _{Eliminates input current errors}
Y _{Interchangeable with LM111}
Y _{No need for input current buffering}
