Philips Semiconductors Product specification
24 W BTL or 2 x 12 watt stereo
car radio power amplifier
TDA1518BQ
GENERAL DESCRIPTION
The TDA1518BQ is an integrated class-B output amplifier in a 13-lead single-in-line (SIL) plastic power package.
The device is primarily developed for car radio applications.
FEATURES
• Requires very few external components
• Flexibility in use stereo as well as mono BTL
• High output power (without bootstrap)
• Low offset voltage at output (important for BTL)
• Fixed gain
• Good ripple rejection
• Mute/stand-by switch
• Load dump protection
• A.C. and d.c. short-circuit-safe to ground and V
P
• Thermally protected
• Reverse polarity safe
• Capability to handle high energy on outputs (VP= 0 V)
• No switch-on/switch-off plop
• Flexible leads
• Low thermal resistance
• Identical inputs (inverting and non-inverting)
• Compatible with TDA1516BQ (except gain).
