■ 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.

■ Features
• The resonance frequency can be freely set by optional selection of the capacitor capacitance.
• Low distortion rate: THD = 0.04% (VCC = 5 V)
• Wide dynamic range: VO = 800 mV[rms] (at Boost THD = 1%)
• Low noise level: Vno = 10 µV (VCC = 5V)
