LC75281E

Ordering number : EN5913 CMOS IC LC75281E Parametric Equalizer System Overview The LC75281E is a four-band stereo parametric equalizer. A parametric equalizer is a fully general equalizer that allows all three parameters that define an equalizer’s characteristics, i.e., the center frequency, gain, and Q, to be set independently. Package Dimensions unit: mm 3159-QFP64E [LC75281E] Functions Four-band (low, low mid, high mid, and high) left and right channels parametric equalizer For each band: Center frequency: 11 positions Gain: 13 positions in ±2dB steps Q: Variable over 8 positions The center frequency, gain, and Q control settings are set using serial data input in the CCB format. Features A parametric equalizer with the following features can be implemented with just two ICs: this IC and a microcontroller. The center frequency, gain, and Q can be controlled by a single operation. Memory recall by a single operation can be implemented using preset values. Either shelving or peaking characteristics can be selected for the low band. SANYO: QFP64E (QIP64E) CCB is a trademark of SANYO ELECTRIC CO., LTD.
