STA369BW
Sound Terminal®
2.1-channel high-efficiency digital audio system
Features
â Wide-range supply voltage
â 5 V to 26 V (operating range)
â 30 V (absolute maximum rating)
â Four power output configurations
â 2 channels of ternary PWM (stereo mode)
(2 x 30 W into 8 Ω at 22 V)
â 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 4Ω, 1 x 8 Ω at 22 V)
â 2 channels of ternary PWM (2 x 30 W) +
stereo lineout ternary)
â FFX®100 dB SNR and dynamic range
â Selectable 32 to 192 kHz input sampling rates
â I2C control with selectable device address
â Digital gain/attenuation +42 dB to -80 dB with
0.125 dB/step resolution
â Soft-volume update with programmable ratio
â Individual channel and master gain/attenuation
â Two independent DRCs configurable as a
dual-band anti-clipper (B2DRC) or independent
limiters/compressors
â EQ-DRC for DRC based on filtered signals
â Dedicated LFE processing for bass boosting
with 0.125 dB/step resolution
â Audio presets:
â 15 preset crossover filters
â 5 preset anti-clipping modes
â Preset nighttime listening mode
â Individual channel and master soft/hard mute
â Independent channel volume and DSP bypass
â Automatic zero-detect mute
â Automatic invalid input-detect mute
â I2S input data interface
â Input and output channel mapping
PowerSSO-36
with exposed pad down (EPD)
â Up to 8 user-programmable biquads per
channel
â 3 coefficient banks for EQ presets storing with
fast recall via I2C interface
â Extended coefficient dynamic up to -4..4 for
easy implementation of high shelf filters
â Bass/treble tones and de-emphasis control
â Selectable high-pass filter for DC blocking
â Advanced AM interference frequency
switching and noise suppression modes
â Selectable high- or low-bandwidth
noise-shaping topologies
â Selectable clock input ratio
â 96 kHz internal processing sampling rate with
quantization error noise shaping for very low
cutoff frequency filters
â Thermal overload and short-circuit protection
embedded
â Video apps: 576 x Fs input mode supported
â Fully compatible with STA339BW,
STA369BWS and STA350BW
