该LMH664X家庭真正的单电源电压反馈型放大器提供高速（130MHz的），低失真（- 62dBc），以及极高的输出电流（约75毫安）在较低的成本和降低功耗具有类似的性能时，对现有设备进行比较。
输入共模电压范围0.5V到低于V - 从V和1V + 。 Any supply rail difference of less than 40mV in the output voltage range is desirable for wide dynamic range, especially in low voltage applications. The output stage is about 75 mA capable of pushing heavy loads. The fast output slew rate (130V/μs) ensures that large peak-to-peak output swings can be maintained at even higher speeds, producing a 3V supply at a special 40MHz full power bandwidth. These features, combined with low cost, make them ideal for a variety of industrial and commercial applications.
Careful attention is paid to ensuring the stability of equipment in all operating voltages and modes. 其结果是一个非常乖巧的频率响应特性以最小的调峰任何增益设置下，重型和轻载时（通常2分贝最大）（0.1分贝高达12MHz的增益平坦度150Ω负载下和AV= +2）。 This makes devices with fast settling times (68ns) and low distortion good for operating in ADC buffers, high-frequency filter applications, and other applications.
This device family offers low DG(0. 01%) and DP (0.01°) featuring professional-quality video performance. 差分增益和差分相位特性也很好的维护下（150Ω）重物和整个输出电压范围。 该LMH664X系列提供单（LMH6642），双（LMH6643），和四（LMH6644）选项。 See Ordering offers for information.
