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鈥檚
characteristics, i.e., the center frequency, gain, and Q, to
be set independently.
Package Dimensions
unit: mm
3159-QFP64E
[LC75281E]
Functions
鈥?Four-band (low, low mid, high mid, and high) left and
right channels parametric equalizer
鈥?For each band:
Center frequency: 11 positions
Gain: 13 positions in 鹵2dB steps
Q: Variable over 8 positions
鈥?The center frequency, gain, and Q control settings are
set using serial data input in the CCB format.
Features
鈥?A parametric equalizer with the following features can
be implemented with just two ICs: this IC and a
microcontroller.
鈥?The center frequency, gain, and Q can be controlled by a
single operation.
鈥?Memory recall by a single operation can be implement-
ed using preset values.
鈥?Either shelving or peaking characteristics can be
selected for the low band.
