(8 ? vrms) 3 ?j possible to realize paramentric equalizer using 3 band tone, and 2 band tone and loudness. 4 ?j built-in ground isolation amplifiter input, ideal for external stereo input and monaural input. (1 stereo input and 2 monaural input) 5 ?j it is using a i 2 c bus control. because it is possible to use at the same time in a maximum of two. 6 ?j bicmos process is suitable for the design of low current (typ.10ma) and low energy. car stereo, mini component stereo, micro component stereo, dvd, personal computer, tv. symbol limits unit ?? absolute maxim um ratings ?i t a=25 c ?j maximum applied voltage power dissipation operating temperature range storage temperature range p ar ameter vcc pd t opr tstg 1 0 . 0 9 5 0 + 8 5 + 1 5 0 - 4 0 - 5 5 ?` ?` mw c c v ?? ?? der ating : 7.6mw/ c f or oper ation abo v e t a=25 c pcb (70mm 70mm 1.6mm glass epo xy board) notes: i 2 c b u s is a trademark of philips incorporated.
