The TAS2562 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.

Integrated speaker voltage and current sense 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 four devices can share a common bus via I2S/TDM + I2C interfaces.

The TAS2562 device is available in a 36-ball, 0.4 mm pitch CSP for a compact PCB footprint.
