Product Folder Sample & Buy Support & Community Tools & Software Technical Documents LMH3402 SBOS744 – JUNE 2016 1 Features 3 Description • • • • • • • • The LMH3402 is a very high-performance, dualchannel, differential amplifier optimized for radiofrequency (RF), intermediate-frequency (IF), or highspeed time-domain applications. This device is ideal for dc- or ac-coupled applications that use differentialto-differential (Diff-Diff) or single-ended-to-differential (SE-Diff) conversion when driving an analog-to-digital converter (ADC). The LMH3402 generates very low levels of second- and third-order distortion when operating in SE-Diff or Diff-Diff mode. 1 • • • • • 3-dB Bandwidth: 7 GHz Excellent Linearity Performance: DC to 2 GHz Selectable Gains: 6 dB, 14 dB, 17 dB (Differential) Channel Gain Matching DC to 1 GHz: < 0.05 dB Channel Phase Matching DC to 1 GHz: < 0.7° Crosstalk at 1 GHz: –70 dBc Slew Rate: 17,500 V/µs Low Harmonic Distortion (2-VPP, 200-Ω, Diff-Diff Configuration) – 500 MHz: HD2 at –78 dBc, HD3 at –78 dBc – 1 GHz: HD2 at –70 dBc, HD3 at –72 dBc – 2 GHz: HD2 at –51 dBc, HD3 at –47 dBc Low Intermodulation Distortion (2-VPP, 200-Ω, Diff-Diff Configuration): – 500 MHz: IMD2 at –85 dBc, IMD3 at –88 dBc – 1 GHz: IMD2 at –70 dBc, IMD3 at –71 dBc – 2 GHz: IMD2 at –51 dBc, IMD3 at –51 dBc Input Voltage Noise: 1.3 nV/√Hz Supports Single- and Dual-Supply Operation Power Consumption: 55 mA per Channel Power-Down Feature 2 Applications • • • • • • • • • GSPS ADC Drivers IQ Demodulation Receivers ADC Drivers for Ultra Wideband or Narrowband Data Acquisition Single-Ended to Differential Signal Converters DAC Buffers IF, RF, and Baseband Gain Blocks SAW Filter Buffers and Drivers Balun Replacement, DC to 2 GHz Level Shifters The device has unprecedented usable bandwidth from dc to 2 GHz with three internal gains of 6 dB, 14 dB, and 17 dB. The LMH3402 can be used as a very wideband ADC driver, and also for SE-Diff conversions in the signal chain without external baluns. The LMH3402 performance is ideal for 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 voltage with the ADC input requirements. Power supplies between 3.15 V and 5.25 V can be selected, and dual-supply operation is supported when required by the application. A power-down feature is also available for saving power. This level of performance is achieved at a very low power level of 280 mW per channel when a 5.0-V supply is used. The LMH3402 is fabricated using Texas Instruments' advanced complementary BiCMOS process, and is available in a space-saving, 24-pin, VQFN package for higher performance.

All other trademarks are the property of their respective owners. 4.6 Electrostatic Discharge Caution This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 4.7 Glossary SLYZ022 — TI Glossary.
