3 Description
The TAS5720x device is a high-efficiency mono
Class-D audio power amplifier optimized for high
transient power capability to use the dynamic power
headroom of small loudspeakers. The device is
capable of delivering more than 15 W continuously
into a 4-Ω speaker.
The digital time division multiplexed (TDM) interface
enables up to eight devices to share the same bus.
The TAS5720x device is available in a 32-pin,
4 mm × 4 mm, VQFN package for a compact PCB
footprint.
