The LMH6734MQX is a triple current-feedback operational amplifier from National Semiconductor, built for high-speed analog signal chains where bandwidth and slew rate are the limiting factors. Its 925 MHz -3 dB bandwidth and 3750 V/µs slew rate mean it can handle fast video signals, pulse edges, and wideband waveforms without the slew-induced distortion that limits voltage-feedback amplifiers at high gain. The current-feedback topology keeps the bandwidth nearly constant as you increase closed-loop gain, so a gain-of-2 or gain-of-5 stage doesn't collapse the frequency response the way a voltage-feedback part would.
Three channels, 80 mA each — multi-line drive without extra buffers
Three independent amplifier circuits on one die, each rated for 80 mA output current, make this a natural fit for RGB video distribution, triple-channel cable drivers, or multi-tap analog front-ends. The 19.5 mA total supply current per chip is reasonable for a triple wideband part — you are not burning a separate LDO for each channel. Supply range covers 3 V to 12 V single supply or ±1.5 V to ±6 V dual, so it works in both single-rail video systems and traditional bipolar analog rails.
Package and mounting — 16-SSOP with QSOP footprint option
No exposed pad, so thermal management relies on the copper plane and airflow; keep the ambient derating in mind if all three channels drive 80 mA into low-impedance loads continuously.
