What are the key features of XBUF634AIDR?

  • 210 MHz 3dB bandwidth with 250 mA output current capability for driving low-impedance and capacitive loads without signal degradation
  • Wide dual supply range supporting up to ±20V maximum for compatibility with high-voltage analog signal chains and instrumentation systems
  • Unity-gain buffer topology with 2 µA maximum bias current minimizing loading of precision signal sources at high frequencies
  • 8-pin SOIC package introduced in 2019 combining small footprint with high-current output for modern high-speed analog designs

What is XBUF634AIDR used for?

The XBUF634AIDR is designed for high-speed signal buffering applications such as driving ADC reference inputs, active filter output stages, and test instrument signal sources that require wide bandwidth with high output current. It is commonly used as a cable driver in video and RF signal distribution systems where its 210 MHz bandwidth and 250 mA drive capability prevent signal degradation over long transmission lines. The ±15V nominal supply range makes it compatible with precision instrumentation and legacy analog signal processing equipment requiring high-voltage headroom.
