Package Dimensions unit: mm 3067-DIP24S [LC75341] 24 13 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. 7.62 6.4 1 21.2 12 0.51min 0.81 1.78 0.48 0.95 unit: mm 3112-MFP24S [LC75341M] 24 13 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.
