The TAS2120 is a mono, digital input Class-D audio amplifier with an integrated Boost for higher power delivery in battery-operated systems.

Device 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 algorithms enable the device to produce best-in-class efficiency across all power regions of operation. The Class-D amplifier is capable of delivering 8.2W output powerusing integrated Class-H Boost.

TAS2120 device supports look-ahead algorithm based optimum boost voltage levels to match the output of audio signal. This provides all the power needed for peak output while significantly reducing the average power consumption.

Up to four devices can share a common bus via I2S/TDM + I2C interfaces. The device also supports five HW Control pins that can configure the device for the desired mode of operation.
