Ordering number : EN5056A CMOS LSI LC75395E Single-Chip Electronic Volume Control System Overview The LC75395E is an electronic volume control that provides volume, balance, five-band equalization and input switching functions. These functions are controlled from serial input data. Package Dimensions unit: mm 3159-QFP64E [LC75395E] Functions • Volume control: The volume control provides 25 attenuation positions: from 0 dB to –17.5 dB in 1.25 dB steps, from –17.5 dB to –25 dB in 2.5 dB steps, from –25 dB to –36.25 dB in 3.75 dB steps and with settings for –41.25 dB, –50 dB, –60 dB and –∞. A balance function can be implemented by controlling the left and right channels independently. • Equalizer: The equalizer function supports ±10 dB control in 2 dB steps in each of the five bands.
