The TAS2020 is a mono, digital input Class-D audio amplifier designed for efficiently driving high peak power into loudspeakers.

TAS2020 is optimized to deliver best battery life for real-use cases of music playback and voice calls. Advanced efficiency optimization features like Y-bridge, and other algorithms enable the device to produce best-in-class efficiency across all power regions of operation. The Class-D amplifier is capable of delivering 3.2W output powerusing external PVDD supply.

Up to four devices can share a common bus via I2S/TDM and I2C interfaces. TAS2020 also supports HW pin based pre-defined controls that can configure the device for desired mode of operation without requiring any I2C controls.
