The LMH6640MF/NOPB: Its 170 V/µs slew rate and 190 MHz -3 dB bandwidth place it in the high-speed class — think video line drivers, ADC front-end buffers, or pulse-amplifier stages in test equipment. The rail-to-rail output swings close to the supply rails, which helps when you are running from a single 5 V or 12 V rail and need maximum dynamic range into the ADC. Supply span runs from 4.5 V to 16 V, so it works across 5 V logic systems and 12 V industrial rails alike.
Slew rate and bandwidth — the speed that decides the fit
A 170 V/µs slew rate means this part can swing a 5 Vpp step in about 30 ns — fast enough for a 10 MHz sine wave without significant slew-induced distortion. The 190 MHz -3 dB bandwidth supports composite video (NTSC/PAL), CCD readout chains, and high-speed data acquisition front ends. If your design only needs a few megahertz of gain-bandwidth, a general-purpose op-amp like the TLV9351 (3.5 MHz, 20 V/µs) costs less and draws less supply current. The LMH6640MF/NOPB is the choice when the signal edge speed or pulse fidelity demands the higher slew rate.
