Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Description

The TAS5101IDAP is a high-performance true digital stereo audio amplifier (TDAA) Power Stage, designed to drive 2 * 15 watts per channel. The TAS5101 incorporates TI's equibit technology and is used in conjunction with a Digital Audio PWM processor (TAS50xx) to deliver high-power, true digital audio amplification. The efficiency of this digital amplifier can be greater than 90%, reducing the size of both the power supplies and heat sinks needed. The TAS5101 accepts a stereo PWM 3.3V input and controls the switching of an internal CMOS H-bridge.

When used with the TAS5101IDAP PWM Processor, system performance of less than 0.09% THD is attainable.

Over-current protection, over-temperature, and under-voltage protections are built into the TAS5101IDAP, safeguarding the H-bridge and speakers against output shorts, over-voltage conditions, and other fault conditions that could damage the system.
