TRUE DIGITAL STEREO AUDIO AMPLIFIER

WITH PWM STEREO POWER OUTPUT STAGE

Internet Music Appliance

Mini/Micro Component Systems

FEATURES

2 × 15 W High-Quality Digital Amplifier Power

Stage

DESCRIPTION

Single-Ended Output

>95-dB Dynamic Range (TDAA System)

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 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.

THD+N < 0.1% (1 kHz, 1 W to 15 W RMS

Into 4 Ω)

Power Efficiency > 90% Into 4-Ω to 8-Ω Load

Low Profile, SMD 32-Pin PowerPAD Package

Requires No Heat-Sink When Using

Recommended Layout

2 × 15-W RMS Continuous Power Into 4 Ω

Self-Protecting Design

3.3-V Digital Interface

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.
