Protector of Speakers and Power Amplifier

TDA1556Q 2 x 22 W stereo BTL differential amplifier with speaker protection

Few peripheral components High output power Low output offset voltage Fixed gain Loudspeaker protection (with diagnostic facility) Differential inputs Dynamic Distortion Detector (DDD) High common mode input signal Very high CMRR Good ripple rejection Mute/stand-by switch Load dump protection Short-circuit safe Thermally protected Reverse polarity safe High energy handling capability at the outputs (VP = 0 V) Electrostatic discharge protection No switch-on/switch-off plop Flexible leads Low thermal resistance
TDA1556Q is a monolithic integrated class-B output amplifier containing two 22 Watt amplifiers in a BTL configuration. The device is contained in a 17-lead single-in-line (SIL) plastic power package. It has two differential inputs and is primarily intended for car booster applications.
