LC75392 is an electronic volume control IC produced by SANYO. It can realize input/output switching, volume and tone control functions by data transmitted over a serial interface.
The LC75392 (DIP‑30SD) and LC75392M (MFP‑30S) are CMOS LSI volume‑control ICs offering input/output switching, independent left‑right balance, and selectable tone‑control characteristics via a serial CCB interface. Four audio channels can be attenuated from 0 dB down to –70 dB in stepped increments.
The document lists package dimensions, absolute maximum ratings, operating ranges, pin functions, equivalent circuits, and performance graphs such as total harmonic distortion and volume‑step characteristics.
