Philips Semiconductors
2 x 22 W BTL stereo car radio power
amplifier with loudspeaker protection
Product specification
TDA1553Q
GENERAL DESCRIPTION
The TDA1553Q is an integrated class-B output amplifier in a 13-lead singe-in-line (SIL) plastic power package.
The circuit contains 2 x 22 W amplifiers in Bridge Tied Load (BTL) configuration. The device is primarily developed for
car radio applications.
Features
• Requires very few external components
• High output power
• Low offset voltage at outputs
• Fixed gain
• Good ripple rejection
• Mute/stand-by switch
• Load dump protection
• AC and DC short-circuit-safe to ground and VP
• Loudspeaker protection (LSP)
• Thermally protected
• Reverse polarity safe
• Capability to handle high energy on outputs (VP = 0 V)
• Protected against electrostatic discharge
• No switch-on/switch-off plop
• Low thermal resistance
• Flexible leads
