power amplifier
TDA1519B
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)
·
AC and DC short-circuit-safe to ground and V P
·
Thermally protected
·
Stereo or BTL application
·
Reverse polarity safe
·
High output power
·
Capability to handle high energy on outputs (V P =
0 V)
·
Low offset voltage at output (important for BTL)
·
No switch-on/switch-off plop
·
Fixed gain
·
Protected against electrostatic discharge
·
Good ripple rejection
·
Identical inputs (inverting and non-inverting)
·
Mute/stand-by switch
·
Compatible with TDA1519A (except output power).
·
Load dump protection

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
m
A)
·
Low mute/stand-by switching current (low cost supply switch)
·
Mute condition.
