LMH672 Datasheet | National Semiconductor

Description The LMH6714/6720/6722 series bine National’s VIP10™ high speed plementary bipolar process with National’s current feedback topology to produce a very high speed op amp. These amplifiers provide a 400MHz small signal bandwidth at a gain of +2V/V and a 1800V/µs slew rate while consuming only 5.6m A from ± 5V supplies. The LMH6714/6720/6722 series offer exceptional video performance with its 0.01% and 0.01˚ differential gain and phase errors for NTSC and PAL video signals while driving a back terminated 75Ω load. They also offer a flat gain response of 0.1d B to 120MHz. Additionally, they can deliver 70m A continuous output current. This level of performance makes them an ideal op amp for broadcast quality video systems. The LMH6714/6720/6722’s small packages (SOIC & SOT23), low power requirement, low noise and distortion allow the LMH6714/6720/6722 to serve portable RF applications. The high impedance state during shutdown makes the LMH6720 suitable for use in multiplexing multiple high speed signals onto a shared transmission line. The LMH6720 is also ideal for portable applications where current draw can be reduced with the shutdown function.
