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.
High large-signal bandwidth and fast slew rates allow National's new devices to drive high-resolution red, green and blue (RGB) video.
The dynamic performance of these amplifiers is ideal for driving single-ended high-speed analogue-to-digital convertors (ADCs).
"Today we're introducing a true gigahertz op amp", said Erroll Dietz, Vice President of National Semiconductor's Amplifier Products Group.

"National's LMH6703 provides a flatter, more stable frequency response at high speeds".
"The LMH6704, also introduced today, provides gain accuracy within 1%, for demanding high-performance applications".
National's LMH6703 is the industry's most stable 1.2GHz amplifier for high-speed signals, making it less dependent on PC board layout compared with most solutions currently on the market.
It features the industry's highest large-signal (2V peak-peak) bandwidth at 750MHz and 4500V/us slew rate for better signal fidelity, resulting in improved performance in high-end video applications with UXGA (1600 x 1200, 75Hz) resolutions and beyond.
Additionally, the LMH6703 has a shutdown feature, provides 0.1dB gain flatness out to 150MHz, and low second/third harmonic distortion of -87/-100dBc at 5MHz for driving single-ended high-speed ADCs.
National's LMH6704 is a 650MHz programmable gain buffer with internal gain-setting resistors, allowing the user to set the gain at -1, +1, or +2.
It provides a shutdown feature, 0.1dB gain flatness out to 200MHz, and low second/third harmonic distortion of -62/-78dBc at 10MHz.
The LMH6704's low differential phase and gain specifications provide less luminance and chrominance distortion when driving composite video signals.
The high output current (90mA) allows both the LMH6703 and LMH6704 to drive low-impedance, high-capacitive loads in any application.
National's LMH6703 and LMH6704 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 utilises deep trench technology on a bonded wafer for complete dielectric isolation and optimal high-speed amplifier performance.
The VIP10 process technology allows National to design the most power-efficient, performance-oriented high-speed amplifiers on the market today.
Specialising in high-performance amplifiers and comparators, National Semiconductor offers a complete portfolio of op amps ranging from building-block chips to application specific standard products (ASSPs), including precision, high-speed, low-power and low-voltage amplifiers.
The company has a long history of innovation in amplifiers, including the first low-voltage op amp and the "amp-in-a-mic".
National also leads the industry in packaging technology with its revolutionary Silicon Dust and micro SMD packaging technologies.
In addition, National's patented VIP10 process technology enables designers to create the industry's broadest suite of high-performance op amps available today.
National's LMH6703 is available now in SOIC-8 and SOT23-6 packages and is priced at $1.49.
The LMH6704 is available now in SOIC-8 and SOT23-6 packages and is priced at $1.49.
Both prices are for 1000-unit quantities.
Lead-free package options are also available.
