APPLICATIONS

DESCRIPTION

The TAS5101 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

t 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 TAS50xx 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 TAS5101,

safeguarding the H-bridge and speakers against output

shorts,

over-voltage

conditions,

and

other

fault

conditions that could damage the system.
