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.
