48-Ball, 0.35mm Pitch, WCSP package

The TAS2573 is a digital input Class-D amplifier with an integrated Boost for higher power delivery in battery-operated systems. The device has integrated IV-Sense for real-time monitoring of the loudspeakers. An on-chip, low-latency DSP supports Texas Instruments SmartAmp speaker protection and audio tuning algorithms to enable high output SPL while keeping speakers in a safe operating region.

The device is optimized for delivering the best battery life with advanced efficiency optimization features like Class-H, Y-bridge and DSP algorithms. An advanced battery guard algorithm on the DSP manages peak output power delivery while avoiding any audio distortion when battery capacity is depleting. This algorithm is supported using a local battery voltage monitor ADC.

Up to four TAS2573 amps can share a common bus via I2S/TDM + I2C interfaces.
