• 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 DRC/AGC function in the TPA2016D2 is
• Power Supply Range: 2.5 V to 5.5 V
programmable via a digital I
