... Operating mode if a byte other than 0xAC is received. Mute mode is activated when the mute silence pattern (at least 32 consecutive 0x66 bytes) is detected on the DATA input. The TFA9881 will switch to Mute mode after byte 32 and will remain in Mute mode until a byte other than 0x66 is received. ...

... Control settings Control settings are not needed if the default values are adequate. 8.4.1 Silence pattern recognition The TFA9881 can detect control settings on the PDM input by means of silence pattern recognition.

... Dynamic Power Stage Activation (DPSA) The TFA9881 uses DPSA to regulate current consumption in line with the level of the incoming audio stream. This function switches off power stage sections that are not needed, reducing current consumption. Each of the TFA9881 H-bridge power stages is divided into eight sections. The number of power stage sections activated depends on the level of the incoming audio stream ...

... Mute Mute mode is activated when the mute silence pattern (at least 32 consecutive 0x66 bytes) is applied on the DATA input. The TFA9881 remains in Mute mode as long as the 0x66 pattern is repeated. It will return to Operating mode when a pattern other than 0x66 is received. Transitions to and from Mute mode occur as soon as the relevant pattern is recognized by the TFA9881 (hard mute and hard unmute) ...

... Remark: The maximum PDM input modulation depth should be limited to avoid false IDP triggering. 8.6.2 OverTemperature Protection (OTP) OTP prevents heat damage to the TFA9881 triggered when the junction temperature exceeds 130 °C. When this happens, the output stages are set floating. OTP is cleared automatically via an internal timer (100 ms with f stages will start to operate normally again ...
