For a 5 V output step, the 3000 V/µs rate translates to a rise time of roughly 1.7 ns, keeping the output faithful to the input up to the 400 MHz small-signal bandwidth ceiling. The differential output architecture means the amplifier drives balanced lines directly — no external balun needed for ADC front-ends or twisted-pair cable runs. The 75 mA per-channel output current is enough to drive a 50-ohm load to ±3.75 V swing, so it handles terminated transmission lines without an extra buffer stage. Supply span runs from 4.5 V to 12 V, covering common 5 V and 12 V rails. Quiescent draw is 20 mA — not a micropower part, but reasonable for a 400 MHz amplifier in a signal-conditioning stage where bandwidth matters more than standby current. ## Package, temperature grade, and shelf life Housed in an 8-SOIC (0.154\", 3.90 mm width) surface-mount package, supplied in tube. The SOIC-8 footprint is a standard JEDEC outline — no special land pattern or thermal-via array needed. The -40°C to 85°C operating range covers industrial and telecom ambient environments; it is not rated for extended automotive or under-hood use. Input bias current is 8 µA and input offset voltage is 1 mV — typical for a high-speed voltage-feedback stage. These figures matter when the amplifier is DC-coupled to a high-impedance source; the 8 µA bias into a 10 kΩ source adds 80 mV of DC error, so AC-coupling or a lower-impedance source is the cleaner path. ## Lifecycle and sourcing posture The tube packaging is standard for sample and low-volume production — no reel or dry-pack concerns for the storeroom.","metaTitle":"Texas Instruments LMH6550MA/NOPB Voltage Feedback Amp","metaDescription":"Active-production TI LMH6550MA/NOPB voltage feedback amplifier, 400 MHz -3dB bandwidth, 3000V/µs slew rate, differential output, 8-SOIC.
