The LT1115 is the lowest noise audio operational amplifier available. This ultralow noise performance (0.9nV/√Hz at 1kHz) is combined with high slew rates (>15V/µs) and very low distortion specifications.

The RIAA circuit shown below using the LT1115 has very low distortion and little deviation from ideal RIAA response (see graph).

Applications

  • High Quality Audio Preamplifiers
  • Low Noise Microphone Preamplifiers
  • Very Low Noise Instrumentation Amplifiers
  • Low Noise Frequency Synthesizers
  • Infrared Detector Amplifiers
  • Hydrophone Amplifiers
  • Low Distortion Oscillators
