2 / 12 page 1998 Sep 23 2 Philips Semiconductors Product specification 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. QUICK REFERENCE DATA ORDERING INFORMATION SYMBOL PARAMETER CONDITIONS MIN.
