Texas Instruments TAS5720x Closed Loop I2S Input Amplifiers

Texas Instruments TAS5720x Closed-Loop I2S Input Amplifiers are a high-efficiency mono Class-D audio power amplifier optimized for high transient power capability. This feature makes them ideal for use in the dynamic power headroom of small loudspeakers. Each of these Texas Instruments TAS5720x Amplifiers can deliver more than 15W continuously into a 4Ω speaker. The digital time division multiplexed (TDM) interface enables up to eight devices to share the same bus. Typical applications include sub-woofers, boom boxes, bar speakers, and surround sound systems.
