LC75395E

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. Of the five bands, four provide peaking characteristics, and one provides shelving characteristics. Selector: The selector function selects one of four inputs for each of the left and right channels. An arbitrary amplification level can be set for each input signal using external components. Serial data input: All controls can be set from serial input data (CCB format) SANYO: QIP64E Features On-chip buffer amplifiers to minimize the number of external components Silicon-gate CMOS process for minimal switching noise On-chip circuit to generate the VDD/2 reference voltage CCB is a trademark of SANYO ELECTRIC CO., LTD.
