LMH5401IRMST

The LMH5401IRMST is a very high-performance Differential Amplifier optimized for intermediate frequency (IF) or high-speed, DC-coupled, time-domain applications. The device is ideal for DC- or AC-coupled applications that may require a single-ended-to-differential (SE-DE) conversion when driving an analog-to-digital converter (ADC). The LMH5401 generates very low levels of second- and third-order distortion when operating in SE-DE or differential-to-differential (DE-DE) mode. The amplifier is optimized for use in both SE-DE and DE-DE systems. The device has unprecedented usable bandwidth from DC to 2GHz. The LMH5401 can be used for SE-DE conversions in the signal chain without external baluns in a wide range of applications such as broadband communications and high-speed data acquisition. A common-mode reference input pin is provided to align the amplifier output common-mode with the ADC input requirements.
