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.
●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.
