LT1115 - Ultra-Low Noise, Low Distortion, Audio Op Amp - Linear Technology（凌力尔特）

功能描述

The LT1115 is the lowest noise audio operational amplifier available. This ultralow noise performance (0.9nV/rtHz 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).

特点

Voltage Noise 1.2nV/ rtHz Max at 1kHz

0.9nV/ rtHz 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@10kHz, AV= -10, RL=600ohms 0.002% VO=7VRMS

Low IMD, CCIF Method, AV= +10: 0.002%, RL=600ohms ,VO=7VRMS
