Key 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 Ω at 18 V) + PWM output
    • 2 channels of ternary PWM (2 x 20 W into 8 Ω at 18 V) + ternary stereo line-out
    • 2.1 channels of binary PWM (left, right, LFE) (2 x 9 W into 4 Ω +1 x 20 W into 8 Ω at 18 V)
  • FFX with 100-dB SNR and dynamic range
  • Scalable FFX modulation index (up to 100%)
  • Selectable 32- to 192-kHz input sample rates
  • I2C control with selectable device address
  • Digital gain/attenuation +48 dB to -80 dB with 0.125-dB/step resolution
  • Soft volume update with programmable ratio
  • Individual channel and master gain/attenuation
  • Two independent DRCs configurable as a dual-band anti-clipper (B2DRC) or as independent limiters/compressors with optional global DRC capability
  • EQ-DRC for DRC based on filtered signals
  • Dedicated LFE processing for bass boosting with 0.125-dB/step resolution
  • Audio presets:
    • 15 preset crossover filters
    • 5 preset anti-clipping modes
    • Preset night-time listening mode
  • Individual channel soft/hard mute
  • Independent channel volume and DSP bypass
  • I2S input data interface
  • Input and output channel mapping
  • Automatic invalid input-detect mute
  • Up to 8 user-programmable biquads/channel
  • Three coefficients banks for EQ presets storing with fast recall via I2C interface
  • Extended filter dynamics +4/-4 for better sound shaping and easier filter implementation
  • Bass/treble tones and de-emphasis control
  • Selectable high-pass filter for DC blocking
  • Advanced AM interference frequency switching and noise suppression modes
  • F3X™ advanced PWM modulation scheme for carrier suppression (headphone or line output)
  • Selectable high- or low-bandwidth noise-
