3 Description

The TAS5815 is a high efficiency digital input Class-

D audio amplifier with integrated audio processor

with up to 96kHz architecture, adaptive modulation

schemes based on output power and low RDS(on)=

120mΩ. It also supports DPEQ process for easy

tuning.

The DPEQ is used to mix the audio signals through

two signal paths (low level and high level). These 2

paths are used with separate equalization properties.

A third path monitors the incoming audio and

determines the thresholds and mixing characteristics

between these two parts. Thus, the mix between the

two high- and low-level channels is dynamic in nature

and depends on the incoming audio.

The high-performance closed loop architecture and

wide-switching frequency range reduces the solution

size by reducing passive components and minimize

the inductor size in most applications. TAS5815 has

an integrated audio processor with up to 96kHz

architecture support advanced process flow. The

device has an integrated a proprietary algorithm

called Class-H. The Class-H algorithm detects the

upcoming audio power demand and provides a PWM

control signal for the former DC-DC converter via

the feedback pin (FB). This feature used to increase

the system-level efficiency and reduce total power

consumption. The TAS5815 supports up to 2.5ms of

delay buffer to look ahead at the audio signal and

prevents audio clipping distortion.

This device also supports speaker load open/short

detection and report detection result with register

report.
