产品介绍
STA369BWS
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
