Description

The TAS2563 is a digital input Class-D audio amplifier optimized for efficiently driving high peak power into small loudspeaker applications. The Class-D amplifier is capable of delivering 6.1 W of peak power into a 4 Ω load at a battery voltage of 3.6 V. TAS2563 supports boost bypass mode (External PVDD mode) where it can achieve 12W at 10% THD+N (4 Ω at 12 V).

An on-chip, low-latency DSP supports Texas Instruments SmartAmp speaker protection algorithms to maximizes loudness while maintaining safe speaker conditions.

Integrated speaker voltage and current sense with internal protection algorithms provides for real time monitoring of the loudspeakers. This permits pushing peak SPL while keeping speakers in the safe operation area. A battery tracking peak voltage limiter with brown-out prevention optimizes amplifier headroom over the entire charge cycle preventing system shutdowns.

Up to eight devices can share a common bus via I2S/TDM + I2C interfaces.

The TAS2563 device is available in a 42-ball, 0.4 mm pitch DSBGA (YBG) for a compact PCB footprint.
