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 (2V_PP). 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.

System power may be optimized using the chip enable feature for the OPA4872.
