• Filter-Free Class-D Architecture

The TPA2016D2 is a stereo, filter-free Class-D audio

power amplifier with volume control, dynamic range

• 1.7 W/Ch Into 8 Ω at 5 V (10% THD+N)

compression (DRC) and automatic gain control

• 750 mW/Ch Into 8 Ω at 3.6 V (10% THD+N)

(AGC). It is available in a 2.2 mm x 2.2 mm WCSP

• 2.8 W/Ch Into 4 Ω at 5 V (10% THD+N)

package and 20-pin QFN package.

• 1.5 W/Ch Into 4 Ω at 3.6 V (10% THD+N)

The
