Description

The LT®1115 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).
