The OPA4872 offers a very wideband 4:1 multiplexer in an SO-14 package. Using only 10.6 mA, the OPA4872 provides a user-settable output amplifier gain with greater than 500-MHz large-signal bandwidth (2 VPP). 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 500-MHz small-signal bandwidth at a gain of 2, the OPA4872 gives a typical 0.1-dB gain flatness to greater than 120 MHz.
System power may be optimized using the chip-enable feature for the OPA4872. Taking the chip enable (EN) line high powers down the OPA4872 to less than 3.4 mA total supply current. Further power reduction to 1.1mA quiescent current can be achieved by bringing the shutdown (SD) line high. Muxing multiple OPA4872s outputs together, then using the chip enable to select which channels are active, increases the number of possible inputs.
