Selection Guide Optimum Noise Performance

Linear Technology continues to add to its portfolio of low noise operational amplifiers. This is not because the physics of noise has changed, but because low noise specifications are being combined with new features such as shutdown, rail-to-rail operation, low power and low voltage operation.

Operational amplifier noise is dependent on input stage operating current, device type (FET (Field-Effect Transistor) or bipolar transistor) and input circuitry. This selection guide is intended to help you identify basic noise tradeoffs and select the best operational amplifiers, new or old, for your application.

  • Quantifying Resistor Thermal Noise and Op Amp Noise
  • Summing the Noise Sources
  • Selecting the Best Op Amps
  • Conclusion
