STA339BWS 2.1-channel 40-watt high-efficiency digital audio system Sound Terminal® is a highly integrated audio system that can be configured as 2-channel, 2.1-channel or 2-channel plus 1 PWM output. It supports multiple audio input formats, including PCM, I2S, DSD, and IF, and has multiple functions, including digital audio processing, power amplification, audio presets, etc.
The STA339BWS is a Sound Terminal device designed as a 2.1-channel, 40-watt high-efficiency digital audio system. It features wide-range supply voltage support from 4.5 V to 21.5 V and offers three power output configurations: two channels of ternary PWM plus a PWM output, two channels of ternary PWM plus a stereo line-out, or 2.1 channels of binary PWM (left, right, LFE). The device supports FFX with 100-dB SNR and dynamic range, scalable modulation indices, and selectable input sample rates from 32 to 192 kHz.
The device delivers 2 x 9 W into 4 Ω plus 1 x 20 W into 8 Ω at 18 V.
The device supports a supply voltage ranging from 4.5 V to 21.5 V.
The digital gain/attenuation has a resolution of 0.5-dB per step.
