FEATURES General • Supply voltage range from 8 to 24 V • Low distortion • Few external components, fixed gain • High output power • Can be used as a stereo amplifier in Bridge-Tied Load (BTL) or quad Single-Ended (SE) amplifiers • Single-ended mode without loudspeaker capacitor • Mute and standby mode with one- or two-pin operation • Diagnostic information for Dynamic Distortion Detector (DDD), high temperature (145 °C) and short-circuit • No switch on/off plops when switching between standby and mute or mute and on; an external RC-network is prescribed to ensure plop-free operation • Low offset variation at outputs between mute and on • Fast mute on supply voltage drops. Protection
TDA8580J
• Short-circuit proof to ground, positive supply voltage and across load; the supply voltage ranges where the different short circuit conditions are guaranteed are given in Chapter “Limiting values” • ESD protected on all pins • Thermal protection against temperatures exceeding 150 °C. GENERAL DESCRIPTION The TDA8580J is a stereo Bridge-Tied Load (BTL) or a quad Single-Ended (SE) amplifier that operates over a wide supply voltage range from 8 to 24 V. This makes it suitable for applications such as television, home-sound systems and active speakers. Because of an internal voltage buffer, this device can be used without a capacitor connected in series with the load (SE application). A combined BTL and 2 × SE application can also be configured (one chip stereo and subwoofer application).
