Philips Semiconductors
2 x 22 W or 4 x 11 W single-ended car
radio power amplifier
Product specification
TDA1558Q
FEATURES
• Requires very few external components
• Flexibility in use Quad single-ended or stereo BTL
• High output power
• Low offset voltage at output (important for BTL)
• 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
• Identical inputs (inverting and non-inverting).
GENERAL DESCRIPTION
The TDA1558Q is a monolithic integrated class-B output
amplifier in a 17-lead single-in-line (SIL) plastic power
package. The device contains 4 x 11 W single-ended or
2 x 22 W BTL amplifiers and has been primarily developed
for car radio applications.
