LF111 Datasheet | National Semiconductor

Description The LF111 LF211 and LF311 are FET input voltage parators 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 parator in applications usually requiring input current buffering Leakage testing long time delay circuits charge measurements and high source impedance voltage parisons 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 the LM311 for application help Features Eliminates input current errors Interchangeable with LM111 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 - 2 TL H 5703 - 1 Top View Order Number LF111H LF111H-MIL or LF311H See NS Package Number H08C C1995 National Semiconductor Corporation TL H 5703 RRD-B30M115 Printed in U S A Absolute Maximum Ratings If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications (Note 8) Total Supply Voltage (V84) Output to Negative Supply Voltage (V74) Ground to Negative Supply Voltage (V14) Differential Input Voltage Input Voltage (Note 1) Power Dissipation (Note 2) Output Short Circuit Duration LF111 LF211 36V 50V 30V g 30V g 15V LF111 LF211 Operating Temp Range LF111 LF211 LF311 Storage Temp Range LF311 LF311 36V 40V 30V g 30V g 15V b 55 C to a 125 C b 25 C to a 85 C 0 C to a 70 C b 65 C to a 150 C b 65 C to a 150 C 500 m W 10 seconds 500 m W 10 seconds Lead Temp (Soldering 10 seconds) ESD rating to be determined 260 C 260 C Electrical Characteristics (LF111 Parameter Input Offset Voltage (Note 4) Input Offset Current (Note 4) Input Bias Current Voltage Gain Response Time (Note 5) Saturation Voltage Strobe On...
