STA369BWS
2.1-channel 40-watt high-efficiency digital audio system Sound Terminal, PowerSSO-36, STM, RoHS
The STA369BWS is an integrated solution of digital audio processing, digital amplifier controls and power output stage to create a high-power single-chip FFX digital amplifier with high-quality and high-efficiency. Three channels of FFX processing are provided. The FFX processor implements the ternary, binary and binary differential processing capabilities of the full FFX processor.
The STA369BWS is part of the Sound Terminal™ family that provides full digital audio streaming to the speakers and offers cost effectiveness, low power dissipation and sound enrichment.
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 Ohm at 18 V) + PWM output
- 2 channels of ternary PWM (2 x 20 W into 8 Ohm at 18 V) + ternary stereo line-out
- 2.1 channels of binary PWM (left, right, LFE) (2 x 9 W into 4 Ohm +1 x 20 W into 8 Ohm 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-shaping topologies
- Selectable clock input ratio
- 96-kHz internal processing sample rate with quantization error noise shaping for very low cut-off frequency filters
- Thermal overload and short-circuit protection embedded
