Amplifiers

180 MHz0.95 nV/√Hz105 V/µslow THDunity-gain stableHVSSOP-8

OPA891DGNR is a single, unity-gain-stable high-speed op amp for low-noise and low-distortion analog signal paths, supplied in an 8-pin PowerPAD HVSSOP package.

Best for

  • Low-noise high-speed ADC drivers
  • Wideband active filters
  • Low-distortion analog signal paths

Avoid if

  • Very high-impedance sources sensitive to microampere-level input bias current
  • Applications requiring confirmed lifecycle or compliance data not supplied here

Check before use

  • Confirm output swing and load current requirements
  • Keep feedback and input traces short
  • Add output isolation for significant capacitive loading
