RIAA Phono preamp based on LM4652.
The RIAA curve looks fine. The Bode diagramm shows approx. 12dB at 20Hz, approx. -7dB at 1kHz and approx. -27dB at 20kHz.
The output voltage is at approx. 870mV @1kHz peak-to-peak (standard consumer line level signal).
Based on typical application circuit from here: https://www.ti.com/lit/ds/symlink/lm4562.pdf
