6570 is a high performance analog multiplexer
optimized for professional grade video and other high fidelity
high bandwidth analog applications. The output amplifier
selects one of two buffered input signals based on the state
of the SEL pin. The LMH6570 provides a 400 MHz band-
width at 2 V
PP
output signal levels. Multimedia and high
definition television (HDTV) applications can benefit from the
LMH6570鈥檚 0.1 dB bandwidth of 150 MHz and its 2200 V/碌s
slew rate.
The LMH6570 supports composite video applications with its
0.02% and 0.05藲 differential gain and phase errors for NTSC
and PAL video signals while driving a single, back terminated
75鈩?load. An 80 mA linear output current is available for
driving multiple video load applications.
The LMH6570 gain is set by external feedback and gain set
resistors for maximum flexibility.
The LMH6570 is available in the 8 pin SOIC package.
