Part Description

The LMH5401 is a very high-performance, differential amplifier optimized for radio frequency (RF), intermediate frequency (IF), or high-speed, dccoupled, 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 (DEDE) mode. The amplifier is optimized for use in both SE-DE and DE-DE systems. The device has unprecedented usable bandwidth from dc to 2 GHz. The LMH5401 can be used for SE-DE conversions in the signal chain without external baluns in a wide range of applications such as test and measurement, 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. Power supplies between 3.3 V and 5.0 V can be selected and dual-supply operation is supported when required by the application. A power-down feature is also available for power savings. This level of performance is achieved at a very low power level of 275 mW when a 5.0-V supply is used. The device is fabricated in Texas Instruments' advanced complementary BiCMOS process and is available in a space-saving, UQFN-14 package for higher performance.
