Multi-purpose power amplifier
Preliminary specification
TDA8580
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.
GENERAL DESCRIPTION
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.
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.
