National Semiconductor launched the world's fastest amplifiers for professional and wideband video applications. The high-speed LMH6738 and LMH6739, both created using National's proprietary VIP10 process technology, are designed for applications requiring high bandwidth and low distortion.
Operating at 750 MHz small signal bandwidth, these high-performance devices drive today's highest-resolution video signals in LCD projectors, multi-media, video switching and routing, conference room and HDTV systems.
The LMH6738 is a wideband, triple, current feedback (CFB) operational amplifier, and the LMH6739 is a wideband, triple, programmable gain buffer (PGB), both operating at 750 MHz small signal bandwidth. Both devices have independent disable pins for each amplifier, feature 7.3ns enable times, and have low crosstalk, allowing them to be used in multiplexing (MUXing) and demultiplexing (deMUXing) applications.
With 400 MHz large signal bandwidth (LSBW), 3300 V/μs slew rate, and a 0.1dB gain flatness of 200 MHz, the LMH6738/39 outperform the competition in driving high-resolution RGB video signals. Additionally, the high output current of 90mA drives low impedance, high capacitive loads in single-ended cable line driving applications.
