TDA8933B

The TDA8933B is designed as one kind of high-efficiency class-D audio power amplifier device that remains operating with considerable music output power without the need for an external heat sink, even for high supply voltages and/or lower load impedances. The device has two full differential inputs driving two Also this device can be used in (1)flat panel television sets; (2)flat panel monitor sets; (3)multimedia systems; (4)wireless speakers; (5)mini and micro systems; (6)home sound sets applications.

Features of the TDA8933B are:(1)Operating voltage from 10 V to 36 V asymmetrical or ±5 V to ±18 V symmetrical; (2)Mono-bridged tied load (full-bridge) or stereo single-ended (half-bridge) application; (3)Application without heat sink using thermally enhanced small outline package; (4)High efficiency and low-power dissipation; (5)Thermally protected and thermal foldback; (6)Current limiting to avoid audio holes; (7)Full short-circuit proof across load and to supply lines (using advanced current protection); (8)Switchable internal or external oscillator (master-slave setting); (9)No pop noise; (10)Full-differential inputs.

The absolute maximum ratings of the TDA8933B can be summarized as:(1)supply voltage: 10 to 36 V;(2)supply current: 145 to 195 uA;(3)total quiescent current: 40 to 50 mA. If you want to know more information about the TDA8933B, please download the datasheet in www.seekic.com or www.chinaicmart.com .
