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) 2x50 W into 6 Ω at 25 V
- 3 channels - left, right using binary and LFE using ternary PWM (2.1 mode) (2x18 W + 1x40 W into 2x4 Ω, 1x8 Ω at 25 V)
- 2 channels of ternary PWM (2x50 W) + stereo lineout ternary
- 1 channel of ternary PWM as mono-BTL 1x90 W into 3 Ω at 24.5 V
