OPA4872
SBOS346C – JUNE 2007 – REVISED MARCH 2011 www.ti.com 4:1 High-Speed Multiplexer
Check for Samples: OPA4872 FEATURES DESCRIPTION The OPA4872 offers a very wideband 4:1 multiplexer
in an SO-14 package. Using only 10.6mA, the
OPA4872 provides a user-settable output amplifier
gain with greater than 500MHz large-signal
bandwidth (2VPP). The switching glitch is improved
over earlier solutions using a new (patented) input
stage switching approach. This technique uses
current steering as the input switch while maintaining
an overall closed-loop design. The OPA4872 exhibits
an off isolation of 88dB in either Disable or Shutdown
mode. With greater than 500MHz small-signal
bandwidth at a gain of 2, the OPA4872 gives a typical
0.1dB gain flatness to greater than 120MHz. 1 2 500MHz SMALL-SIGNAL BANDWIDTH
