DESCRIPTION
The LT®1115 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.

FEATURES
■ 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, AV = –10, RL = 600Ω: 0.002% VO = 7VRMS
■ Low IMD, CCIF Method, AV = +10: 0.002% RL = 600Ω VO = 7VRMS

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
