TAS2562 Class-D Audio Amplifier

Texas Instruments TAS2562 Class-D Audio Amplifier is a digital input Class-D audio amplifier optimized for efficiently driving high peak power into small loudspeaker applications. The Class-D amplifier can deliver 6.1W of peak power into a 4Ω load at a battery voltage of 3.6V. Integrated speaker voltage and current sense provide for real-time monitoring of the loudspeakers. This feature 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 Texas Instruments TAS2562 devices can share a common bus via I²S/TDM + I²C interfaces.
