370 MHz differential amp — what it drives and where it sits
The Texas Instruments LMH6551MM/NOPB is a voltage-feedback amplifier with a differential output, 370 MHz -3dB bandwidth, 2400 V/µs slew rate, 3 V to 12 V supply span, and -40°C to 125°C temperature range.
What the ratings mean on the bench
The 370 MHz bandwidth is the small-signal limit. The 2400 V/µs slew rate supports fast edge handling. Input offset voltage is 500 µV typical. Quiescent current is 12.5 mA per channel.
Package and footprint
The LMH6551MM/NOPB comes in an 8-VSSOP package (3.00 mm width, 0.118" body). That's a small outline for a high-speed part — keep the feedback resistor close to the pins and use a solid ground plane under the package to avoid parasitic inductance killing the bandwidth. The /NOPB suffix confirms ROHS3 compliance, no lead in the finish.
