Footprint and integration — SOT-23-6 thin
The LMH6618MK/NOPB comes in a SOT-23-6 Thin (TSOT-23-6) package, with the supplier device package designated as SOT-23-THIN. This is a surface-mount footprint with a 0.65 mm typical lead pitch, demanding a standard two-layer PCB layout with adequate thermal vias under the package if dissipating near the 35 mA output current limit at elevated temperatures.
Speed and drive — what the slew rate means for your signal chain
A 57 V/µs slew rate combined with 140 MHz -3 dB bandwidth and 65 MHz gain-bandwidth product means this voltage-feedback op-amp can swing a 5 Vpp output at frequencies up to roughly 1.8 MHz before slew-rate limiting kicks in. For a 2 Vpp signal, the full-power bandwidth extends to about 4.5 MHz — enough for high-speed ADC drivers, video buffers, or pulse-processing front-ends. With 35 mA output current capability, it drives 50-ohm or 75-ohm terminated lines with adequate margin for a single video or communications channel.
DC precision and power budget
The 1.35 mA supply current per channel is the trade-off for the 57 V/µs slew rate; a lower-power op-amp in the same package would draw under 0.5 mA but slew at 10 V/µs or less.
