GENERAL DESCRIPTION
The TDA1519B 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.
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 V
P
Thermally protected
Reverse polarity safe
Capability to handle high energy on outputs (V
P
=
0 V)
No switch-on/switch-off plop
Protected against electrostatic discharge
Identical inputs (inverting and non-inverting)
Compatible with TDA1519A (except output power).

PINNING
FUNCTIONAL DESCRIPTION
The TDA1519B contains two identical amplifiers with differential input stages. The gain of each amplifier is fixed at
40 dB. A special feature of this device is the mute/stand-by switch which has the following features:
Low stand-by current (
<
100
A)
Low mute/stand-by switching current (low cost supply switch)
Mute condition.
