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.
