Triple 300MHz Amplifiers Drive Video and LCDs


Posted on Oct 15, 2012

With the advent of HDTV and DVD video, there is a renewed focus on RGB and color-difference component video to maximize picture quality. LCD displays have also entered the mainstream for high-end and portable computer displays. These applications often require high speed triple amplifiers for routing and conditioning video signals. With these applications in mind, Linear Technology has introduced the LT®1399 and LT1399HV triple current feedback amplifiers. The LT1399 and LT1399HV contain three independent 300MHz current feedback amplifiers, each with a shutdown pin.



Each amplifier has exceptional 0.1dB gain flatness of 150MHz and a slew rate of 800V/ms. Output drive current is a minimum of 80mA over temperature. The LT1399 operates on all supplies from a single 4V to ±6V. If higher supply voltages are require
