quad BTL car radio power amplifier

Preliminary specification

TDA8591J

1 FEATURES

• Low quiescent current

• Low distortion

• Low output offset voltage

• Soft thermal clipping to prevent audio holes

• External mute timer for low start-up plop (also allows a

fast mute function)

• High output power

• Operating, mute and standby mode selection by two-pin

or single-pin operation

• Diagnostic information available:

– Dynamic Distortion Detection (DDD)

– High temperature detection

– Short-circuit detection

– Detection of output offset due to leakage current at

the input

• No switch-on/switch-off plops when switching between

standby and mute modes or between mute and

operating modes

• Fast mute with supply voltage drops

• Package with flexible leads

• All outputs can withstand short-circuits to ground, to the

positive supply voltage and across the load

• Pin CP can withstand short-circuits to its adjacent pins,

all other pins can withstand short-circuits to ground and

to the positive supply voltage

• ESD protection on all pins

• Thermal protection against junction temperatures

exceeding 150 °C

• Load dump protection

• Protected against open ground pins (loss of ground) and

outputs short-circuited to supply ground

• All negative outputs are protected against open supply

voltage and output short-circuited to supply voltage

• Reverse-polarity safe.

2 GENERAL DESCRIPTION

The TDA8591J is a quad BTL audio power amplifier

comprising four independent amplifiers in Bridge Tied

Load (BTL) configuration. Each amplifier has a gain of

26 dB and supplies an output power of 75 W (EIAJ) into a

2 Ω load. The TDA8591J has low quiescent current and is

primarily developed for car audio applications.
