SBOS444 – DECEMBER 2008 4:1 HIGH-SPEED MULTIPLEXER • Video Router 2 • 500-MHz Small-Signal Bandwidth • LCD and Plasma Display • 500-MHz, 2-V PP Bandwidth • High Speed PGA • 0.1-dB Gain Flatness to 120 MHz • Drop-In Upgrade to AD8174 • 10-ns Channel-Switching Time • Low Switching Glitch: 40 mV PP • 2300-V/µs Slew Rate AND MEDICAL APPLICATIONS • 0.035%/0.005° Differential Gain, Phase • Controlled Baseline • Quiescent Current = 10.6 mA • One Assembly/Test Site • 1.1-mA Quiescent Current in Shutdown Mode • One Fabrication Site • Available in Military (–55°C/125°C), • 88-dB Off Isolation in Disable or Shutdown Temperature Range(1) (10 MHz) • Extended Product Life Cycle • Extended Product-Change Notification • Product Traceability (1) Additional temperature ranges available - contact factory 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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
