特性 Features

 High power capability:

– 40 W/4  max

– 35 W/4  EIAJ

– 45 W/3.2  max

– 40 W/3.2  EIAJ

– 32 W/3.2  @ VS = 14.4 V, f = 1 kHz,

d = 10 %

– 26 W/4 @ VS = 14.4 V, f = 1 kHz,

d = 10%

 DIfferential inputs (either single ended or

differential input signal are accepted)

 Minimum external component count:

– No bootstrap capacitors

– No Boucherot cells

– Internally fixed gain (30 dB)

– No SVR Capacitor

 Standby function (CMOS compatible)

 Programmable turn-on/off delay

 No audible pop during mute and standby

operations

 Protections:

– Short circuit (to GND, to VS, across the

load)

– Very inductive loads

– Chip over temperature

– Load dump

– Open GND

– ESD
