The TAS2120 is a mono, digital input Class-D audio amplifier with an integrated Boost for higher power delivery in battery-operated systems.
TAS2120 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 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 and I2C interfaces. TAS2120 also supports HW pin based pre-defined controls that can configure the device for desired mode of operation without requiring any I2C controls.
