TDA 1519B(AUDIO OUTPUT AMPLIFIER); 2 SPEAKER MODEL

(1) Features

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)

(2) General Description

The TDA 1519B is an integrated class-B dual output amplifier in a 9-lead single in-line(SIL) plastic medium power package. The device is primarily developed for car radio applications.
