TDA8563AQ

The TDA8563AQ is an integrated class-B output amplifier in a 13-lead single-in-line (SIL) power package. It contains 2 ´ 40 W/2 W amplifiers in a BTL configuration.The device is primarily developed for car radio applications.

TDA8563AQ has many unique features: The first one is it requires very few external components.The second one is high output power.The third one is low output offset voltage.The forth one is diagnostic facility (distortion, short-circuit and temperature pre-warning).The fifth one is good ripple rejection.The sixth one is mode select switch (operating, mute and standby).The seventh one is load dump protection.The eighth one is short-circuit safe to ground and to VP and across the load.The ninth one is Low power dissipation in any short-circuit condition.The tenth one is thermally protected.
