1 / 20 page  October 13, 2008 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.
