Ordering number : ENN7308
CMOS IC
LC75348, 75348M
Single-Chip Electronic Volume and
Tone Control System
Overview
The LC75348 and LC75348M are electronic volume and
tone control ICs that provide volume, balance, 2-band
equalizer, input gain control, and input switching
functions while requiring a minimal number of external
components.
Functions
• Volume: 81 levels: 0 dB to –79 dB (in 1 dB steps) and
–∞.
The left and right channels are controlled independently,
allowing a balance function to be implemented.
• Bass: Peaking characteristics bass control with ±20 dB
range in 2 dB steps.
• Treble: Shelving characteristics treble control with ±10
dB range in 2 dB steps.
• Selector: One of 4 inputs can be selected for both left
and right channels.
• Input gain: Input signal amplification from 0 to +30 dB
(in 2 dB steps)
Features
• Built-in buffer amplifiers reduce the number of external
components required.
• Fabricated in a silicon gate CMOS process for minimal
switching noise from built-in switches and minimal
switching noise even when there is no input signal.
• Built-in zero cross circuits minimize switching noise
when input signals are present.
• Built-in V_DD/2 reference voltage generator circuit.
• All functions are controlled from serial data. Supports
the CCB bus.
