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

plastic DIL-bent-SIL power package; 27 leads (lead length 7.7 mm)
• 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.

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.
