The LMH3401 is a very high-performance, differential amplifier optimized for radio frequency (RF), intermediate frequency (IF), or high-speed, time-domain applications. This device is ideal for dc- or ac-coupled applications that require a single-ended to differential conversion when driving an analog-to-digital converter (ADC). The LMH3401 generates very low levels of second-order and third-order distortion when operating in single-ended-input to differential-output or differential-input to differential-output mode.
The on-chip resistors simplify printed circuit board (PCB) implementation and provide the highest performance over the usable bandwidth of 2 GHz. This performance makes the LMH3401 ideal for 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. Use this device with power supplies between 3.3 V and 5.0 V; dual-supply operation is supported when required by the application.
This level of performance is achieved at a very low power level of 275 mW when a 5.0-V supply is used. A power-down feature is also available for power savings. The LMH3401 is fabricated in Texas Instruments' advanced complementary BiCMOS process and is available in a space-saving, 14-lead UQFN package with a specified operating temperature range of –40°C to 85°C.
