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 15V range the LF111

can be used in the most critical applications.

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

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.

Eliminates input current errors

Interchangeable with LM111

No need for input current buffering
