What this current-feedback amp is built for
The current-feedback architecture means the bandwidth holds up as you increase the gain, unlike a voltage-feedback amp where gain and bandwidth trade directly.
A 2700 V/µs slew rate means this amp can swing its output rail-to-rail in under 5 ns. That matters for video at 1080p rates where a slow amp softens the sync edges, or for driving the input of a high-speed ADC where the sampling aperture needs a settled signal. The 115 mA output current per channel gives it enough drive to handle a 75 Ω coax line directly, though you still want a back-termination resistor for impedance matching.
Supply range and thermal limits
The LMH6732 runs on a supply span from 9 V to 12 V, which covers the common ±5 V split-rail or a single 12 V rail. Quiescent supply current is 9 mA per amplifier, so in a single-channel design the total power dissipation is modest. The SOT-23-6 package is small enough for dense boards but has a thermal pad on the underside; if you push the output current near the 115 mA limit continuously, a via stitch to a ground plane keeps the junction temperature in check.
The "NOPB" suffix confirms it is lead-free / RoHS-compliant, which is the standard for new builds.
