TAS5142 General Description

The TAS5142 is a third-generation, high-performance, integrated stereo digital amplifier power stage with an improved protection system. The TAS5142 is (1) It is not recommended to drive 200 W (total capable of driving a 4-W bridge-tied load (BTL) at up power) into the DDV package continuously.

to 100 W per channel with low integrated noise at the For multichannel systems that require two output, low THD+N performance, and low idle power channels to be driven at full power with the dissipation. DDV package option, it is recommended to design the system so that the two channels A low-cost, high-fidelity audio system can be built are in two separate devices.

using a TI chipset, comprising a modulator (e.g., TAS5508) and the TAS5142. This system only re- PurePath Digital™ quires a simple passive LC demodulation filter to Please

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) These voltages represent the dc voltage + peak ac waveform measured at the terminal of the device in all conditions.
