EVM中提到:
The TPA3223EVM supports both AD modulation as well as HEAD modulation. In AD mode, each of the two half-bridge outputs are continuously switching. AD mode is the default mode for the TPA3223EVM. The EVM also supports HEAD mode modulation. HEAD mode also switches both half bridge outputs but also optimizes the switching for lower power loss at idle as well as increased EMI performance at cost of some performance. The device accomplishes this by reducing its duty cycle at idle and while playing small signals. At higher output levels HEAD mode will also reduce the switching on one of the half bridges. The modulation mode can be controlled through jumper J6 on the EVM as follows:
12引脚为HEAD;但是在规格书中,12引脚为GND
请问HEAD是否确认有此功能?
