The LMH6572 is a high performance analog multiplexer optimized for professional grade video and other high fidelity, high bandwidth analog applications. The LMH6572 provides a 290-MHz bandwidth at 2-VPP output signal levels. The 140 MHz of 0.1-dB bandwidth and a 1500-V/µs slew rate make this part suitable for high definition television (HDTV) and high resolution multimedia video applications.The LMH6572 supports composite video applications with its 0.02% and 0.02° differential gain and phase errors for NTSC and PAL video signals while driving a single, back terminated 75-Ω load. The LM6572 can deliver 80-mA linear output current for driving multiple video load applications.The LMH6572 has an internal gain of 2 V/V (+6 dBv) for driving back terminated transmission lines at a net gain of 1 V/V (0 dBv).The LMH6572 is available in the SSOP package.
