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
·
Thermally protected
·
Flexibility in use ¾ stereo as well as mono BTL
·
Reverse polarity safe
·
High output power (without bootstrap)
·
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
·
Flexible leads
·
Good ripple rejection
·
Low thermal resistance
·
Mute/stand-by switch
·
Identical inputs (inverting and non-inverting)
·
Load dump protection
·
Compatible with TDA1516BQ (except gain).
·
A.C. and d.c. short-circuit-safe to ground and V P

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