TDA8569Q Audio Amplifier 4 x 40W

TDA8569Q 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.  TDA8569Q Audio Amplifier 4 x 40W 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.

Description
The TDA7566 is a new BCD technology quad bridge type of car radio amplifier in Flexiwatt25  package specially intended for car radio applications. Thanks to the DMOS output stage the TDA7566 has a very low distortion allowing a clear powerful sound. This device is equipped with a full diagnostics array that communicates the status of each speaker through the I2C bus.The possibility to control the configuration and behavior of the device by means of the I2C bus makes TDA7566 a very flexible product.
