3 Description
The TAS5822M is a High Efficiency digital input
Class-D audio amplifier for driving loudspeakers used
in consumer, commercial, and industrial electronics. .
– Supports stereo bridge-tied or mono parallel
bridge-tied loads (BTL and PBTL)
Efficient class-D operation:
– > 90% power efficiency, 90 mΩ RDSon
Supports multiple output configurations
– 2 × 35 W in 2.0 Mode (8-Ω, 24 V, THD+N=1%)
– 2 × 22 W in 2.0 Mode (6-Ω, 18 V, THD+N=1%)
Excellent audio performance:
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. TAS5822M has
an integrated audio processor with up to 96-kHz
architecture support advanced process flow.
•
•
This device supports high efficiency 1SPW
modulation with adjustable Class D loop bandwidth to
achieve good audio performance.
•
•
– THD+N ≤ 0.06% at 1 W, 1 kHz, PVDD = 24 V
– SNR ≥ 110 dB (A-weighted), ICN ≤ 40 μVRMS
