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鈥檚 Equibit錚?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.
