Description
AI
The TAS2572 is a digital input Class-D audio amplifier with an integrated Boost for higher power delivery in battery-operated systems. The device has integrated speaker voltage and current sense (IV-Sense) for real-time monitoring of the loudspeakers. IV-sense data can be used to run speaker protection algorithms on a host DSP to enable high output SPL while keeping speakers in a safe operating region.
The device is optimized for delivering the best battery life for real use cases of Music playback and Voice calls. Advanced efficiency optimization features like Class-H , 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 6.6 W output power using the integrated Class-H 13 V Boost.
A battery tracking peak voltage limiter and a battery voltage monitor ADC enables advanced battery monitoring algorithms on the host processor to manage peak output power delivery while avoiding any audio distortion when battery capacity is depleting.
Up to four devices can share a common bus via I 2S/TDM + I 2C interfaces.
