LMH6643MA Datasheet PDF - TI

The LMH6643MA is a 130MHz 75mA rail-to-rail output Low-power Amplifier offers high speed (130MHz), low distortion and exceptionally high output current approximately 75mA with reduced power consumption when compared against existing devices with similar performance. Input common mode voltage range 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 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. Careful attention has been paid to ensure device stability under all operating voltages and modes. The result is a very well behaved frequency response characteristic with minimal peaking for any gain setting and under both heavy and light loads.
