4 × 40 W BTL quad car radio
power amplifier
Product specification
TDA8569Q
FEATURES
• Capable of driving 2 Ω loads
• 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, 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 TDA8567Q.
GENERAL DESCRIPTION
The TDA8569Q is an integrated class-B output amplifier in
a 23-lead Single-In-Line (SIL) plastic power package.
It contains four amplifiers in Bridge-Tied Load (BTL)
configuration, each with a gain of 26 dB. The output power
is 4 × 40 W in a 2 Ω load.
APPLICATIONS
• The device is developed primarily for car radio
applications.
