LMH6642QMF/NOPB

LMH664X 系列是真正的单电源电压反馈放大器，可提供高速(130MHz) 低失真(−62dBc) 特性和超高输出电流（约75mA），成本和功耗更低。 输入共模电压范围扩展至下限V−以下 0.5V，上限V+以上 1V。各电源轨输出电压范围扩展至 40mV 以内，允许较宽的动态范围，尤其适用于低压应用。输出级能够输出约 75mA 的电流以驱动较大负载。高速输出转换率 (130V/μs) 可确保较大的峰峰值输出摆幅即使在更高的速度条件下也能保持不变，从而在3V 电源下输出优异的40MHz 满功率带宽。器件的上述特性及低成本优势是多种工业和商业应用的理想特性。 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 (0.1dB gain flatness up the 12MHz under 150Ω load and A_V =+2) with minimal peaking (typically 2dB maximum) for any gain setting and under both heavy and light loads. This along with fast settling time (68ns) and low distortion allows the device to operate well in ADC buffer, and high frequency filter applications as well as other applications. This device family offers professional quality video performance with low DG (0.01%) and DP (0.01°) characteristics. Differential Gain and Differential Phase characteristics are also well maintained under heavy loads (150Ω) and throughout the output voltage range. The LMH664X family is offered in single (LMH6642) and dual (LMH6643).
