D2-1 Family Audio SOC
D2-1 Family for Manufacturers of High-Performance Class-D Audio Amplifiers
The D2 Audio DSP D2-1 Family (D2-81412,
D2-81431,
D2-81433,
and
D2-81435)
is a fully self-contained 4-channel
digital amplifier controller System-On-Chip (SOC). The D2-1
Family enables rapid system design for manufacturers of
home theater receivers, multi-room distributed audio systems,
and powered speakers.
The D2-1 Family contains a high-performance digital switching
controller to play any input source on any output channel.
A configurable audio signal processor provides equalization,
volume control, tone control, and compression for each
channel, as well as crossover and power limiting for powered
speaker applications.
The D2-1 Family includes 4-channels I
2
S/left-justified inputs
(16-bit to 24-bit, 32kHz to 192kHz) and an optional S/PDIF
receiver (16-bit to 24-bit).
Boot options include: Self-boot from an external serial ROM,
asynchronous SCI slave boot, and serial slave boot from a host
microcontroller.
See the Ordering Information table on
page 3
for additional
information about support for D2 Audio DSP Sound
Enhancement Algorithms firmware, as well as for SRS Labs™
and Dolby Labs™ algorithm support.

1. These Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate
plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). The Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
