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.
