TDA1518BQ
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
P
Thermally protected
Reverse polarity safe
Capability to handle high energy on outputs (V
P
= 0 V)
No switch-on/switch-off plop
Flexible leads
Low thermal resistance
Identical inputs (inverting and non-inverting)
Compatible with TDA1516BQ (except gain).

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