2
× 25 W BTL stereo car radio power amplifier
with differential inputs and diagnostic outputs
TDA8566Q
FEATURES
• Differential inputs
• Very high Common Mode Rejection Ratio (CMRR)
• High common mode input signal handling
• Requires very few external components
• High output power
• 4 Ω and 2 Ω load driving capability
• Low offset voltage at output
• 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 proof to ground, to VP and across the load
• Low power dissipation in any short-circuit condition
• Thermally protected
• Reverse polarity safe
• Protected against electrostatic discharge
• No switch-on/switch-off plop
• Flexible leads
• Low thermal resistance.
GENERAL DESCRIPTION
The TDA8566Q is an integrated class-B output amplifier
contained in a 17-lead single-in-line (SIL; bent to DIL)
plastic power package. The device contains two amplifiers
in a Bridge-Tied Load configuration (BTL). The output
power is 2
× 25 W in a 4 Ω load or 2 × 40 W in a 2 Ω load.
It has a differential input stage and two diagnostic outputs.
The device is primarily developed for car radio
applications.
