National Semiconductor has announced the DP83862, a low-cost, highly integrated dual-port 10/100/1000 physical layer transceiver.
World's smallest multifunction supervisory ICs
National Semiconductor has announced a family of supervisory ICs with a variety of factory-programmable features that can be configured in hundreds of possible combinations.
"National is focused on providing high-speed, high-performance amplifiers with the highest bandwidth, fastest slew rates, and lowest distortion in the industry", said Erroll Dietz, Vice President of National's Amplifier Product Group.
"The LMH6738/39 are prime examples of National providing excellent signal fidelity with low harmonic distortion for high-quality video performance in high-resolution applications".
National's LMH6738 is wideband, triple, current feedback (CFB) operational amplifier, and the LMH6739 is a wideband, triple, programmable gain buffer (PGB), both operating at 750MHz 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 and demultiplexing applications.
With 400MHz large signal bandwidth (LSBW), 3300V/us slew rate, and a 0.1dB gain flatness of 200MHz, the LMH6738/39 outperform the competition in driving high-resolution red, green, blue (RGB) video signals.
Additionally, the high output current of 90mA drives low impedance, high capacitive loads in single-ended cable line driving applications.
National's LMH6738/39 are the latest amplifiers in a new series of high-speed products based on the VIP10 process.
Developed in National's wafer fabrication site in Arlington, Texas, VIP10 is a high-speed, dielectrically isolated, complementary bipolar IC process that uses deep trench technology on a bonded wafer for complete dielectric isolation and optimal high-speed amplifier performance.
VIP10 is the process technology that allows National to design the most power-efficient, performance-oriented high-speed amplifiers on the market today.
National's LMH6738 is available now in SSOP-16 packaging and is priced at $2.95.
The LMH6739 is available now in SSOP-16 packaging and is priced at $3.15.
Both prices are for 1000-unit quantities.
