2 × 24 W BTL or 4 × 12 W single-ended
car radio power amplifier
Product specification
TDA8561Q
FEATURES
• Requires very few external components
• High output power
• Flexibility in use; Quad single-ended or stereo BTL
• Low output offset voltage
• Fixed gain
• Diagnostic facility (distortion, short-circuit and
temperature detection)
• Good ripple rejection
• Mode select switch (operating, mute and standby)
• Load dump protection
• AC and DC short-circuit safe to ground and to VP
• Low power dissipation in any short-circuit condition
• Thermally protected
• Reverse polarity safe
• Electrostatic discharge protection
• No switch-on/switch-off plop
• Flexible leads
• Low thermal resistance
• Identical inputs (inverting and non-inverting).
GENERAL DESCRIPTION
The TDA8561Q is an integrated class-B output amplifier in
a 17-lead single-in-line (SIL) power package. It contains
4 × 12 W Single-Ended (SE) or 2 × 24 W Bridge-Tied
Load (BTL) amplifiers.
The device is primarily developed for car radio
applications.
