Anleitung Zusammenfassung
General description The TDA8566 is an integrated class-B output amplifier which is available in several packages. TDA8566TH is contained in a 20-lead small outline plastic package. The TDA8566TH1 is a 24-lead small outline plastic package which is pin compatible with the I2C-bus controlled amplifier TDA1566TH for one board layout. TDA8566Q is a 17-pin DIL-bent-SIL package. The device contains 2 amplifiers in a Bridge-Tied Load (BTL) configuration. The output power is 2 . 25 W in a 4 W load or 2 . 40 W in a 2 W load. It has a differential input stage and 2 diagnostic outputs. The device is primarily developed for car radio applications. 2. 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 W and 2 W 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 plops . Low thermal resistance . TDA8566TH1 is pin compatible with TDA1566TH NXP Semiconductors NXP Semiconductors 2 .40 W/2 W stereo BTL car radio power amplifier 3. Quick reference data Table 1.
