Overview

Voltage Noise:
- 1.2nV/√Hz Max at 1kHz
- 0.9nV/√Hz Typ at 1kHz
Voltage and Current Noise 100% Tested
Gain-Bandwidth Product: 40MHz Min
Slew Rate: 10V/µs Min
Voltage Gain: 2 Million Min
Low THD at 10kHz, A_V= –10, R_L= 600Ω: 0.002%, V_O= 7V_RMS
Low IMD, CCIF Method, A_V= +10: 0.002%, R_L= 600Ω, V_O= 7V_RMS

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
