TAS5110A General Description
The TAS5110A is a high-performance true-digital audio amplifier (TDAA) power stage, designed to drive 50 W per channel. The TAS5110A incorporates TI's Equibit and PurePath Digital 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 TAS5110A accepts a mono PWM 3.3-V input and controls the switching of an internal CMOS H-bridge.
When used with the TAS50xx PWM processor, system performance of less than 0.09% THD is attainable.
Overcurrent protection, overtemperature, and undervoltage protections are built into the TAS5110A, safeguarding the H-bridge and speakers against output shorts, overvoltage conditions, and other fault conditions that could damage the system.

(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.
