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).
