3 Description
The LMH6570 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 bandwidth at 2-VPP output signal levels. Multimedia and high
definition television (HDTV) applications can benefit
from the 0.1-dB bandwidth of 150 MHz and the 2200-
V/μs slew rate of LMH6570.
The LMH6570 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 75-Ω 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.
