AN7333S
4-Element Graphic Equalizer IC for Radio/Radio Cassette Recorder
I
Overview
The AN7333S is an integrated circuit for 4-
element graphic equalizers most suitable for radio
cassette / portable component stereo equipment.
2-channel 4-element graphic equalizer can be
configured by applying frequency setting capacitors
and variable resistors externally. Non-step adjust-
ment of the boost and the cutting quantitiy is possible
by variable resistors.
