lmh6643ma

Product Summary

The lmh6643ma is a true single supply voltage feedback amplifier. It offers high speed (130MHz), low distortion (-62dBc), and exceptionally high output current (approximately 75mA) at low cost and with reduced power consumption when compared against existing devices with similar performance. Input common mode voltage range of lmh6643ma extends to 0.5V below V- and 1V from V+. Output voltage range extends to within 40mV of either supply rail, allowing wide dynamic range especially desirable in low voltage applications. The output stage of lmh6643ma is capable of approximately 75mA in order to drive heavy loads. Fast output Slew Rate (130V/μs) ensures large peak-to-peak output swings can be maintained even at higher speeds, resulting in exceptional full power bandwidth of 40MHz with a 3V supply. These characteristics of LMH6643MM, along with low cost, are ideal features for a multitude of industrial and commercial applications.
