Overview
The LC7535M is an electronic volume and loudness control IC that provides volume, balance, and loudness functions with a minimal number of external components and that can be controlled electronically.

Functions
• Volume: Provides 81 positions from 0 dB to –79 dB in
   1-dB steps and –∞. A balance function can be
   implemented by controlling the left and right volume
   levels independently.
• Loudness: A loudness function can be implemented by
   attaching external capacitors at the output tap provided
   at the –20-dB position in the 5-dB step volume control.
• S (select) pin: Up to two LC7535M chips can be used on
   the same bus.
• Serial data input: The LC7535M supports
   communication with the controller in the CCB format.

Feature
• High voltage-handling capacity: ±16 V.
