LF211 - 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 appli

Key Features

  • Y Eliminates input current errors Y Interchangeable with LM111 Y No need for input current buffering Schematic Diagram Note Do Not Ground Strobe Pin or Balance Strobe Pin See Note 7 Connection Diagram Metal Can Package TL H 5703.
