LMH6720  Product Folder

The LMH6714/6720/6722 series combine National's VIP10™ high speed complementary 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 5.6mA 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 75 load. They also offer a flat gain response of 0.1dB to 120MHz. Additionally, they can deliver 70mA 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.
