Features

 Wide-range supply voltage

– 5 V to 26 V (operating range)

– 30 V (absolute maximum rating)

 Four power output configurations

– 2 channels of ternary PWM (stereo mode)

(2 x 30 W into 8  at 22 V)

using ternary PWM (2.1 mode) (2 x 15 W +

1 x 30W into 2 x 4, 1 x 8  at 22 V)

– 2 channels of ternary PWM (2 x 30 W) +

stereo lineout ternary)
