Product speciï¬cation
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 à 25 W in a 4 ⦠load.
APPLICATIONS
⢠The device is primarily developed for car radio
applications.
