22 W BTL or 2 x 11 W stereo car radio
power amplifier
Product specification
TDA1519A
GENERAL DESCRIPTION
The TDA1519A is an integrated class-B dual output amplifier in a 9-lead single in-line (SIL) plastic power package.
The device is primarily developed for car radio applications.
Features
• Requires very few external components for Bridge Tied
Load (BTL)
• Stereo or BTL application
• 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 V)
• No switch-on/switch-off plop
• Protected against electrostatic discharge
• Low thermal resistance
• Identical inputs (inverting and non-inverting)
• Compatible with TDA1519B (except output power).
