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.
I Features
• The resonance frequency can be freely set by op-
tional selection of the capacitor capacitance.
• Low distortion rate: THD = 0.04% (V_CC = 5 V)
• Wide dynamic range: V_O = 800 mV[rms] (at Boost
THD = 1%)
• Low noise level: V_no = 10 µV (V_CC = 5V)
