3 Description

The TAS5802 is a 2×22 W digital input Class-D audio

amplifier for driving loudspeakers used in consumer,

commercial, and industrial electronics. The device

is highly flexible, allowing operation with a range of

control methods, power supply configurations, and

audio I/O arrangements.

The TAS5802 high-performance closed-loop

architecture and wide-switching frequency range

reduce the solution size by reducing passive

components and eliminating the inductor +

capacitor (LC) filters in most applications.

Advanced electromagnetic interference (EMI)

reduction techniques allow excellent electromagnetic

compliance (EMC) performance, even when used with

ferrite bead + capacitor (BC) filters. Several power

consumption methods have been implemented to

minimize idle power consumption (IPC).
