FEATURES
General
•
Operating voltage from 8 to 28 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’ to ‘mute’ and from ‘mute’ to ‘on’
•
Low offset variation at outputs between ‘mute’ and ‘on’
•
Fast mute on supply voltage drops.
Protection
•
Reverse polarity safe
•
Short-circuit proof to ground, positive supply voltage on
all pins and across load
•
ESD protected on all pins
•
Thermal protection against temperatures exceeding
150
°C
•
Load dump protection
•
Protected against open-circuit ground pins and output
short-circuited to supply ground.

PACKAGE
NAME
DBS17P
DESCRIPTION
plastic DIL-bent-SIL power package; 17 leads (lead length 12 mm)
GENERAL DESCRIPTION
TDA8580
The TDA8580 is a stereo bridge-tied load (BTL) or a quad
single-ended amplifier that operates over a wide supply
voltage range from 8 to 28 V. This makes it suitable for
many applications, such as car radios, television and
home-sound systems.
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.
