TFA9842AJ

The TFA9842AJ is designed as one kind of 7.5 W stereo power amplifier device that contains two identical audio power amplifiers. And this device contains a unique protection circuit that is solely based on multiple temperature measurements inside the chip.

Features of the TFA9842AJ are:(1)2 channel SE: 1 W to 7.5 W operation possibility; (2)Soft clipping; (3)Input clamps; (4)Volume control; (5)Standby and Mute mode; (6)No on or off switching plops; (7)Low standby current; (8)High supply voltage ripple rejection; (9)Outputs short-circuit protected to ground, supply and across the load; (10)Thermally protected. And the TFA9842AJ can be used in wide range of applications such as (1)CRT TV and LCD TV; (2)Monitors; (3)PC speakers; (4)Boom box; (5)Mini and micro audio receivers.

The absolute maximum ratings of the TFA9842AJ can be summarized as:(1)supply voltage: -0.3 to +28 V;(2)repetitive peak output current: 3 A;(3)junction temperature: 180 °C;(4)storage temperature: -55 to +150 °C;(5)ambient temperature: -40 to +85 °C;(6)total power dissipation: 35 W;(7)short-circuit protection supply voltage: 26 V.
