power amplifier

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

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 µA)

• Low mute/stand-by switching current (low cost supply switch)

• Mute condition.
