该TAS5142是第三代，高性能，具有完善的保护系统集成立体声数字放大器功率级。 该TAS5142是能够驾驶着4 -桥接高达负载（BTL）每通道100瓦的低噪声输出集成，低THD + N性能和低功耗闲置。

一种低成本，高保真音响系统可以建立使用TI​​的芯片组，包括一个调制器（例如，TAS5508）和TAS5142。 This system requires only a simple passive LC filter, demodulated and proven EMI compliant to provide high-quality, high-efficiency audio amplification. 这个装置需要两个功率为12 GVDD和VDD V和32 V电源为PVDD。 该TAS5142不需要上电顺序，由于内部上电复位。
