Technical content

The ZXFBF04 is a low cost, high slew rate, quad buffer amplifier. Built using the Zetex CA700 technology, this buffer has a small signal bandwidth of greater than 100MHz and a 1 volt pk-pk bandwidth of greater than 20 MHz. Each channel draws only 1.9mA. The device operates from a ±5 volt supply, which makes it ideal in a majority of applications. This space saving buffer may be used in a wide variety of applications such as, video switching matrix, multi-channel instrumentation equipment, and A/D input buffer, etc. FEATURES AND BENEFITS

  • 4 Buffers per package
  • 100MHz bandwidth
  • Low cost
  • Low supply current (1.9mA per buffer)
  • No thermal runaway
  • 14 pin SOIC package

APPLICATIONS

  • Video Switching Matrix input buffer
  • Instrumentation
  • Multi-channel A/D input buffer
  • Multi-isolation buffer PART NUMBER PACKAGE PART MARK ZXFBF04N14 SOIC14N ZXFBF04
