Philips Semiconductors Product specification
4×25 W BTL quad car radio poweramplifier 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 Ω load.
APPLICATIONS
•The device is primarily developed for car radio
applications.
