Breaking barriers

National Semiconductor today introduced two new high-speed amplifier products that break the gigahertz speed barrier.

Based on National's high-speed VIP10 manufacturing process, the 1.2 GHz amplifier and programmable gain buffer enable high signal fidelity and stability for improved performance in high-speed applications such as video, test and measurement, and other industrial applications.

High large-signal bandwidth and fast slew rates allow National's new devices to drive high-resolution red, green and blue (RGB) video. The performance of these amplifiers is said to be ideal for driving single-ended high-speed analogue-to-digital converters (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 one percent, for demanding high-performance applications."

National's LMH6703 is said to be the industry's most stable 1.2 GHz amplifier for high-speed signals, making it less dependent on PC board layout compared to most solutions currently on the market. It features the industry's highest large-signal (2Vpp) bandwidth at 750 MHz and 4500V/us slew rate for better signal fidelity, resulting in improved performance in high-end video applications with UXGA (1600 x 1200, 75 Hz) resolutions and beyond.
