- Low total harmonic distortion (0.002%)  
- High output drive capability  
- Stable with capacitive loads  
- Internally compensated  

This information is based on STMicroelectronics' official documentation.

Application Scenarios & Design Considerations

Low-noise op-amps

Alternative Part Number

  • LM833DT --: Dual low-noise audio operational amplifier with similar bandwidth and noise performance, available in the same SO-8 package and pinout, making it a direct drop-in replacement.
  • NE5532DR --: Industry-standard dual low-noise op-amp with comparable or better noise and drive characteristics, widely available in SOIC-8 and suitable for audio and general-purpose applications.
  • OPA2134UA --: High-performance dual audio op-amp with low distortion and low noise, pin-compatible in SOIC-8, offering improved audio quality where the circuit can tolerate slightly different supply and slew characteristics.
