DESCRIPTION

The TAS5101 is a high-performance true digital stereo

audio amplifier (TDAA) Power Stage, designed to drive

脳

15 watts per channel. The TAS5101 incorporates

TI鈥檚 equibitt 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.
