Overview

Ordering number : ENN*6271 CMOS IC LC75342, 75342M Single-Chip Volume and Tone Control System Preliminary Overview The LC75342 and LC75342M are electronic volume and tone control systems that provide volume, balance, a 2band equalizer, and input switching functions that can be controlled from serially transferred data.
Package Dimensions unit: mm 3196-DIP30SD [LC75342] 30 16 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.
