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 50 W into 6 Ω at 25 V)

  – 3 channels - left, right using binary and LFE using ternary PWM (2.1 mode) (2 x 18 W + 1 x 40 W into 2 x 4 Ω, 1 x 8 Ω at 25 V)

  – 2 channels of ternary PWM (2 x 50 W) + stereo lineout ternary

  – 1 channel of ternary PWM as mono-BTL (1 x 90 W into 3 Ω at 24.5 V)
