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
