Preliminary specification
TDA8511J
FEATURES
• Requires very few external components
• High output power
• Fixed gain
• Diagnostic facility (distortion, short-circuit and
temperature detection)
• Good ripple rejection
• Mode select switch (operating, mute and standby)
• 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.
APPLICATIONS
The device is primarily developed for multi-media
applications and active speaker systems.
GENERAL DESCRIPTION
