Philips Semiconductors Product specification
4×25 W BTL quad car radio power
amplifier TDA8567Q
FEATURES
Requires very few external components
High output power
Low output offset voltage
Fixed gain
Diagnostic facility (distortion, short-circuit and
temperature pre-warning)
Good ripple rejection
Mode select switch (operating, mute and standby)
Load dump protection
Short-circuit safe to ground and to VP and across the
load
Low power dissipation in any short-circuit condition
Thermally protected
Reverse polarity safe
Electrostatic discharge protection
No switch-on/switch-off plop
Flexible leads
Low thermal resistance
Pin compatible with the TDA8568Q, except for the gain.
GENERAL DESCRIPTION
The TDA8567Q is an integrated class-B output amplifier in
a 23-lead Single-In-Line (SIL) plastic power package.
It contains four amplifiers in BTL configuration, each with a
gain of 26 dB. The output power is 4×25 W in a 4 load.
APPLICATIONS
The device is primarily developed for car radio
applications.
