Ordering number : EN5588 CMOS LSI LC75373E Electronic Volume Control for Car Stereo Systems Overview The LC75373E is an electronic volume control that can implement volume, balance, fader, bass/treble + super bass, loudness, input switching, and input/output level control functions with a minimal number of external components. Package Dimensions unit: mm 3148-QFP44MA [LC75373E] Functions • Volume: Provides 81 positions, from 0 dB to –79 dB (in 1-dB steps) and – ∞ . A balance function can be implemented by controlling the left and right channels independently. • Fader: This function can attenuate either the rear or the front outputs over 16 positions. (From 0 to –20 dB in 2-dB steps, from –20 to –25 dB in one 5-dB step, from –25 to –45 dB in 10-dB steps, –60 dB, and –∞.
