7-element graphic equalizer IC for Hi-Fi audio equipment n Overview The AN7337NS is a graphic equalizer IC for high performance Hi-Fi audio equipment developed for deck. It incorporates an output buffer circuit and 7 resonance buffer circuits, and can set resonance frequency by ex- ternal capacitor. n Features

  • Low distortion (max.: 0.03%)
  • Low noise voltage (input short circuit: max.: 30 mV[rms])
  • High output voltage (typ. 9.5 V) n Applications
  • Mini-component stereo, system component stereo n Block Diagram SOP020-P-0300B Unit : mm 0.3 0° to 10° 0.15 12.6±0.3 11 0 20 11 5.4±0.3 7.7±0.3 1.27(0.60) Seating plane Seating plane 0.40±0.25 0.1±0.1 1.5±0.2 0.65 GND -V CC +V CC
