7-Element Graphic Equalizer IC for Hi-Fi
s Overview
The AN7337N is a graphic equalizer IC for high perfor-
mance Hi-Fi developed for deck. It incorporates output
buffer circuit and 7 resonance buffer circuits, can set res-
onance frequency by external capacitor.
s Features
• Low noise : V_no = 4µVrms typ.
• Low distortion : THD = 0.002% typ. (at V_O = 1Vrms)
• High output power : V_O (max.) = 9.5Vrms typ. (at. THD =
0.1%)
• Wide operating supply voltage range : V_{CC (opr.)} = ±4 ~
±18V
