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.
