Texas Instruments  TAS5722LRSMR

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. 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.
