feature

? Flexible power supply configuration

- Supply voltage range PVDD: 4.5V to 26.4V

- DVDD and I/O: 3.3V or 1.8V

? Output power

- 2×26W, stereo output (8Ω, 22V, THD+N = 1%)

- 2×21W, stereo output (4Ω, 15V, THD+N = 1%)

- 2X30W (heat sink), stereo output (4Ω, 18V, THD+N =

1%)

? Excellent audio performance
