The LT
®
1115 is the lowest noise audio operational ampli-
fier 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).
