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.
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 implement-
ed using preset values.
• Either shelving or peaking characteristics can be
selected for the low band.
