LMH6714/ LMH6720/ LMH6722/ LMH6722Q Wideband Video Op Amp; Single, Single with Shutdown and Quad LMH6714/ LMH6720/ LMH6722/ LMH6722Q October 20, 2009 Wideband Video Op Amp; Single, Single with Shutdown and Quad General Description The LMH6714/LMH6720/LMH6722 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/LMH6720/LMH6722 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.
