Next generation 23-W Stereo, 26V Closed-Loop Digital Input Audio Class-D Amplifier: TAS5805M

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.
