Product specification
2 x 22 W BTL stereo car radio power
amplifier with speaker protection
TDA1557Q
FEATURES
• Requires very few external components
• High output power
• Low offset voltage at output
• Fixed gain
• Good ripple rejection
• Mute/stand-by switch
• Load dump protection
• AC and DC short-circuit-safe to ground and VP
• Thermally protected
• Reverse polarity safe
• Capability to handle high energy on outputs (VP = 0)
• Protected against electrostatic discharge
• No switch-on/switch-off plop
• Flexible leads
• Low thermal resistance.
GENERAL DESCRIPTION
The TDA1557Q is a monolithic integrated class-B output
amplifier in a 13-lead single-in-line (SIL) plastic power
package. The device contains 2
× 22 W amplifiers in BTL
configuration and has been primarily developed for car
radio applications.
