Power Stage
• Requires very few external components for
Bridge Tied Load(BTL)
• Stereo ot 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=OV)
• No switch-on/switch-off plop
• Protected against electrostatic discharge
• Identical inputs(inverting and non-inverting)
• Compatible with TDA 1519A(except output power)
