TDA8945

The TDA8945 is designed as one kind of single-channel audio power amplifier device that can be used in wide range of applications such as:(1)Mains fed applications (e.g. TV sound); (2)PC audio; (3)Portable audio. Also this device is printed-circuit board (PCB) compatible with all other types in the TDA894X family.

Features of the TDA8945 are:(1)few external components; (2)fixed gain; (3)standby and mute mode; (4)no on/off switching plops; (5)low standby current; (6)high supply voltage ripple rejection; (7)outputs short-circuit protected to ground, supply and across the load; (8)thermally protected; (9)printed-circuit board compatible.

The limiting values of the TDA8945 can be summarized as:(1)supply voltage: -0.3 to +25 V;(2)input voltage: -0.3 to Vcc+0.3 V;(3)repetitive peak output current: 2 A;(4)storage temperature: -55 to +150 °C;(5)operating case temperature: -40 to +70 °C;(6)total power dissipation: 14 W;(7)supply voltage to guarantee short-circuit protection: 18 V.

The static characteristics of this TDA8945 can be summarized as:(1)quiescent supply current: 18 to 28 mA;(2)standby supply current: 10 uA;(3)DC output voltage: 9 V;(4)differential output voltage offset: 200 mV;(5)mode selection input current: 20 uA.
