Intelligent Digital Amplifier PWM Controller and

Audio Processor

D2-45057, D2-45157

Features

• All Digital Class-D Amplifier and Controller with

Integrated Digital Signal Processing (DSP)

The D2-45057 and D2-45157 devices are complete

System-on-Chip (SoC) Class-D digital audio amplifiers.

Combining high performance integrated Power Stages

along with an optimized Audio Processor feature set and

PWM Controller, these devices offer a complete,

powerful, and very cost effective audio solution for high

volume and cost-critical products.

• Four Integrated Power Stages Supporting

- 2 Channels, Bridged

- 4 Channels, Half-Bridge

- 2 Channels, Half-Bridge, plus 1 Channel Bridged

• Output Power (Bridged)

- 25W (8Ω, <1% THD); 30W (8Ω, <10% THD)

This 4th generation Digital Audio Engine (DAE-4P)™

device combines extensive integrated Digital Signal

Processor (DSP) audio processing with amplifier control,

for a complete audio solution. Its ease of integration into

the existing system processor provides complete support

for all system product and amplifier functions.

• Fully Programmable Digital Signal Processing (DSP)

- Up to 5 Programmable Audio Signal Path Channels

- Programmable Equalizers, Filters, Mixers, Limiters

• Includes D2Audio™ SoundSuite™ and

The four configurable Power Stages operate as four

separate Half-Bridge outputs, as two Full-Bridge outputs,

or in combinations of Half-Bridge plus Full-Bridge,

providing flexible loudspeaker drive solutions. Separate

PWM outputs provide additional combinations to drive

headphone, or line level stereo and subwoofer outputs.

SRS WOW/HD™ Audio Enhancement Algorithms

• I S and S/PDIF™ Digital Audio Inputs

• Asynchronous Sample Rate Converters;

Sample Rates from 32kHz up to 192kHz

• Wide 9V to 26V Power Stage HV Supply Range, plus

Internally-Generated Gate Drive Supply

• Temperature and Undervoltage Monitoring

and Individual Channel Protection
