Application Scenarios & Design Considerations

850MHz/ Low Distortion Programmable Gain Buffer Amplifier

Alternative Part Number

  • EL2030CN --: High-speed current-feedback op-amp in DIP-8 with comparable bandwidth and slew rate, suitable drop-in for video and buffer applications.
  • AD844ANZ --: Widely available current-feedback op-amp in DIP-8 offering similar high-speed performance and a well-documented replacement path.
  • LT1223CN8 --: High-speed current-feedback amplifier in DIP-8 with comparable bandwidth and drive capability, usable as a functional substitute.
  • AD811AN --: Wideband current-feedback operational amplifier in PDIP-8 offering similar high-speed performance and a well-established drop-in option for HFA-series video amplifiers.
  • LT1227CN8 --: High-speed current-feedback amplifier in PDIP-8 with comparable bandwidth and drive capability, suitable as a functional substitute where the HFA1112IP is unavailable.
  • LM7171AIN --: Very high-speed voltage-feedback op-amp in DIP-8 with high slew rate and output current, suitable where the HFA1112 is used for fast signal buffering.
