Datasheet

- production data

Features

 Wide-range supply voltage, 4.5 V to 21.5 V

 Three power output configurations:

– 2 channels of ternary PWM (2 x 20 W into

8

 at 18 V) + PWM output

– 2 channels of ternary PWM (2 x 20 W into

8

 at 18 V) + ternary stereo line-out

– 2.1 channels of binary PWM (left, right,

LFE) (2 x 9 W into 4

 +1 x 20 W into 8 

at 18 V)
