LMH6574MA

TEXAS INSTRUMENTS  LMH6574MA  芯片, 4:1多路复用器 高速

The is a high-performance Analog Multiplexer optimized for professional grade video and other high fidelity high bandwidth analog applications. The output amplifier selects any one of four buffered input signals based on the state of the two address bits. The LMH6574 provides a 400-MHz bandwidth at 2Vpp output signal levels. Multimedia and high definition television HDTV applications can benefit from the LMH6574 0.1dB bandwidth of 150MHz. The LMH6574 supports composite video applications with its 0.02% and 0.05° differential gain and phase errors for NTSC and PAL video signals while driving a single, back terminated 75R load. An 80mA linear output current is available for driving multiple video load applications. The LMH6574 gain is set by external feedback and gain set resistors for maximum flexibility.
