TDA1518BQ
car radio power amplifier
GENERAL DESCRIPTION
The TDA1518BQ is an integrated class-B output amplifier in a 13-lead single-in-line (SIL) plastic power package.
The device is primarily developed for car radio applications.
FEATURES
• Requires very few external components
• Flexibility in use stereo as well as mono BTL
• High output power (without bootstrap)
• Low offset voltage at output (important for BTL)
• Fixed gain
• Good ripple rejection
• Mute/stand-by switch
• Load dump protection
• A.C. and d.c. short-circuit-safe to ground and V

FUNCTIONAL DESCRIPTION
The TDA1518BQ contains two identical amplifiers with differential input stages. This device can be used for stereo or
bridge applications. 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.
