Enhanced zero-detect mute and input level measurement
(address 0x50-0x54, 0x2E, 0x2F and 0x5E)
The STA381BWS implements an RMS-based zero-detect function (on serial input interface
data) able to detect in a very reliable way the presence of an input signal, so that the power
bridge outputs can be automatically connected to ground.
When active, the function will mute the output PWM when the input level become less than
“threshold - hysteresis”. Once muted, the PWM will be unmuted when the input level is
detected greater than “threshold + hysteresis”.
The measured level is then reported (for each input channel) on registers 0x51 - 0x52, 0x53
- 0x54 according to the following equation:
Value_in_dB = 20*Log10(Reg_value/(2
16*0.635))
