FEATURES
Protection
General
·
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”
·
Supply voltage range from 8 to 24 V
·
Low distortion
·
Few external components, fixed gain
·
ESD protected on all pins
·
High output power
·
Thermal protection against temperatures exceeding
150
·
Can be used as a stereo amplifier in Bridge-Tied Load
(BTL) or quad Single-Ended (SE) amplifiers
°
C.
·
Single-ended mode without loudspeaker capacitor
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.
·
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
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).
·
Low offset variation at outputs between mute and on
·
Fast mute on supply voltage drops.
