LM7341 Rail-to-Rail Input/Output
±15V, 4.6 MHz GBW, Operational Amplifier in SOT-23
Package
General Description
The LM7341 is a rail-to-rail input and output amplifier in a
small SOT-23 package with a wide supply voltage and tem-
perature range. The LM7341 has a 4.6 MHz gain bandwidth
and a 1.9 volt per microsecond slew rate, and draws 0.75 mA
of supply current at no load.
The LM7341 is tested at −40°C, 125°C and 25°C with modern
automatic test equipment. Detailed performance specifica-
tions at 2.7V, ±5V, and ±15V and over a wide temperature
range make the LM7341 a good choice for automotive, in-
dustrial, and other demanding applications.
Greater than rail-to-rail input common mode range with a
minimum 76 dB of common mode rejection at ±15V makes
the LM7341 a good choice for both high and low side sensing
applications.
LM7341 performance is consistent over a wide voltage range,
making the part useful for applications where the supply volt-
age can change, such as automotive electrical systems and
battery powered electronics.
The LM7341 uses a small SOT23-5 package, which takes up
little board space, and can be placed near signal sources to
reduce noise pickup.
