National Semiconductor Introduces New Family of High-Speed, 1mA Current Feedback Amplifiers For Communications and Video Applications

National Semiconductor LMH6723 LMH6724 LMH6725

LMH6723 (click for larger image) June 7, 2004 - National Semiconductor Corporation launched three new high-speed LMH® amplifiers for portable communications and video applications. The LMH6723, LMH6724 and LMH6725 current feedback (CFB) amplifiers, created using National's unique VIP10 process technology, are designed for applications requiring high-speed performance with very low power consumption. With this key mix of high speed, high output current and low power, these new amplifiers integrate National's strengths in analog design and processing technology.

National's LMH6723/24/25 are single, dual and quad CFB operational amplifiers that provide high speed (370MHz), low power (1mA) and high output current (+110mA) for higher performance, less heat generation and longer battery life in portable applications.

The LMH6723/24/25 also offer 100MHz, 0.1dB gain flatness and low differential phase and gain, along with 100mA linear output current, for high-performance RGB video line driving. This level of performance, obtained while consuming only 1mA of power, as well as the wide supply range of 4.5V to 12V and small package size, makes these amplifiers ideal for a variety of portable applications. These range from handheld walkie-talkies to phone surveillance camera systems, as well as other applications requiring premium high-speed performance with nominal power consumption.

Pricing and Availability
National's LMH6723 is available now in SOIC-8 and SOT23-5 packaging and is priced at $1.25. The LMH6724 is available now in SOIC-8, will soon be available in MSOP-8 packaging and is priced at $1.75. The LMH6725 is available now in SOIC-14, will soon be available in TSSOP-14 packaging and is priced at $2.50. All prices are for 1,000-unit quantities.
