CMOS IC
LC75341, 75341M
Single-Chip Volume and Tone Control System
Preliminary
Overview
The LC75341 and LC75341M are electronic volume and
tone control systems that provide volume, balance, a 2-
band equalizer, and input switching functions that can be
controlled from serially transferred data.
Functions
• Volume: 0 dB to –79 dB (in 1-dB steps) and –∞, for a
total of 81 settings.
The volume can be controlled independently in the left
and right channels to implement a balance function.
• Bass boost: Up to +20 dB in 2-dB steps. Peaking
characteristics.
• Treble: ±10 dB in 2-dB steps. Shelving characteristics.
• Selector: One of four sets of left/right inputs can be
selected.
• Input gain: The input signal can be boosted by from
0 dB to +30 dB in 2-dB steps.
Features
• On-chip buffer amplifiers minimize the number of
external components.
• Fabricated in a silicon gate CMOS process to minimize
switching noise from internal switches.
• Built-in analog ground reference voltage generation
circuit.
• All controls can be set from serially transferred data.
Supports the CCB standard.

LC75341, 75341M
Control System Timing and Data Format
Applications control the LC75341 and LC75341M by applying the stipulated serial data to the CL, DI, and CE pins. This
data consists of a total of 40 bits, of which 8 bits are the address and 32 bits are the data itself.
• Address code (B0 to A3)
The LC75341 and LC75341M have an 8-bit address code, and can be used together with other ICs that support the
Sanyo CCB serial bus format.
