STA369BW-2.1-channel high-efficiency digital audio system Sound Terminal®
2.1-channel high-efficiency digital audio system
Sound Terminal®Datasheet - production dataFeatures 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 30 W into 8 at 22 V)
– 3 channels - left, right using binary and LFE
using ternary PWM (2.1 mode) (2 x 15 W +
1 x 30 W into 2 x 4, 1 x 8 at 22 V)
– 2 channels of ternary PWM (2 x 30 W) +
stereo lineout ternary) FFX®100 dB SNR and dynamic range Selectable 32 to 192 kHz input sampling rates I2C control with selectable device address Digital gain/attenuation +42 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 independent
limiters/compressors
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 nighttime listening mode Individual channel and master soft/hard mute Independent channel volume and DSP bypass Automatic zero-detect mute Automatic invalid input-detect mute I2S input data interface Input and output channel mapping Up to 8 user-programmable biquads per
channel 3 coefficient banks for EQ presets storing with
fast recall via I2C interface Extended coefficient dynamic up to -4..4 for
easy implementation of high shelf filters
Bass/treble tones and de-emphasis control Selectable high-pass filter for DC blocking Advanced AM interference frequency
