LM392 Datasheet, PDF (1/5 Pages) National Semiconductor (TI) – Low Power Operational Amplifier/Voltage Comparator

LM392
Low Power Operational
Amplifier and Comparator
The LM392 contains two functions: an op amp and a comparator.
Both devices can operate on single−supply power and both have a
common−mode range down to ground. Operation from split power
supplies is also possible. Low power−supply current is independent of
the supply voltage level. The output of the comparator interfaces
directly with either TTL or CMOS logic. Low quiescent current makes
the LM392 ideal for portable equipment.
Features
• Wide Power−Supply Range: 3 V to 32 V
• Low Input Offset Voltage: 2 mV
• Low Quiescent Current: 600 mA
• Input CMV Range includes GND
• Op Amp is Unity Gain Stable
• These Devices are Pb−Free and are RoHS Compliant
Typical Applications
• Level Detectors
• Voltage Controlled Oscillators
• Transducer Amplifiers
