LC75281E
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.
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.
