Product Overview

The OPA4872ID is a very wideband 4:1 Multiplexer that 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. 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 3.4mA 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.
  • 500MHz, 2Vpp Bandwidth

  • 2300V/µs Slew rate
  • 0.035%/0.005° Differential gain, phase
  • 10.6mA Quiescent current
  • 88dB OFF isolation in disable or shutdown (10MHz)
  • Drop-In upgrade to AD8174
