3 Description
The TAS5722L device is a high-efficiency mono
Class-D audio power amplifier which includes
integrated digital output clipper, several gain options,
and a wide power supply operating range to enable
use in a multitude of applications. It operates with a
nominal supply voltage from 4.5 V to 17 VDC.
TAS5722L is optimized for high transient power
capability to utilize the dynamic power headroom of
small loudspeakers. It is capable of delivering more
than 15 W of continuous power into a 4-Ω speaker.
The digital time division multiplexed (TDM) interface
enables up to 8 devices to share the same bus.
The TAS5722L device is available in a 4 mm × 4 mm,
32-pin QFN package which can be utilized for a
compact PCB footprint.
